You just can't beat the simplicity and reliability of a small block Chevy. 🇺🇸💯
Ed Cole was the head engineer over the project. He untimely passed away in 1977 but was able to see how ubiquitous the SBC became.
@@leerusch7392 👍🏻 no doubt. Only problem I ever had with the sb is the distributor is up against the firewall and more difficult to work on than Ford or Dodge
@@IRONHEAD12701 But, away from the fan. Maybe I was the only one who fed it.
@@busterdee8228 I was what was known as a “fender mechanic”. Only worked over the grill when the engine was off.

I love watching Nick run around like a mad man. Many of us can relate to that mentality. Cheers my Canadian brothers 🍻.

The 350 belongs to a small club known as one of the best engines ever made. I had one and I beat that engine like a rented mule. Just bolt ons, cam, headers, carb, etc. 168,000 miles and it never left me.
One of the best????? How about THE best.
@@billclisham8668 Not going to disagree but you have to admit the 327 and 283 engines stood shoulder to shoulder with the 350. They were beastly little motors.
@@Slugg-O, I meant the small block Chevy in general.
I had a 327 350 hp from a '65 Vette in a '72 Vega.
@@OldGriz708 I had a '70 4-bolt truck 350 in my '73 Vega!
Jusr chevys,, many poepel dont like them, theya re what they are.
Can't wait until George's inline-6 engine runs on Nick's Dyno. I'm also a big GM and Ford engine fan.
Is it a 2 or 4 bolt main
@@VictorScrayven-gm4bl Nick never said since some else built it.
@@rickh8380 or the year of the block. With a on piece it's best to let center it self before tightening
@@VictorScrayven-gm4bl Thanks for the info. I do believe he thinks it's a 2 piece rear seal. Thanks for the info.
@@VictorScrayven-gm4blNick and George (and Manny) made a video of the tear down of that motor. Pretty sure you will see and find out all you want in that video.
Mopar guy here. Just finished building my 440. Runs great. I also freshened up my 340 and it too runs great. My cousin drove his 87 Chevy truck in the shop. And we pulled the 305 and dropped in a built 350. A week later he drove it home. Everything seems to be good and it makes good power. I have only helped on a few Chevies and this one went together really easy. It might be that it had the hood, grill and fenders off when he brought it. With the air gap intake and 4150 Edelbrock 750 carb along with the aluminum heads and almost .500 lift cam it looked really nice. Chrome valve covers and red wires. I think I will send him this video. He should get a kick out of it. Thanks Nick sending a big “hey” from Kannapolis NC.
😎🇺🇸🤙 sweet rides! Keep em going brotha!
Nice and thanks for watching.
I had a 1975 Chevy truck and a 1070 Monte Carlo with 350’s in them I have also rebuilt a few for some people after retiring from the military in 2011 .. I helped one of my employees rebuild his 350
While in the Army had a new 83 C10 with 305 4barrel SB ...kept the oil change with Texco oil and Fram Filter got to over 405,000 miles before the no#8 cylinder started fouling plug ...It was a great engine for everyday and move quick .
I remember in 1976 , we build a 350 LT 1 engine for a 1969 Camaro SS . We did everything we could and beat this engine and it just never broke. We had the machine shop do the machining for us, and we assembled it in my fathers small 2 car garage.
Those were the days , with no Dyno . Tune and take it for a test drive. Adjust as needed.
Nick is just a master at tuning an engine. Great job Nick.
@@mattdegrange6274 yes sir those where the days, my wife and I have 1 daughter, 3 sons, our little girl can change her on oil, tires, spark plugs n wires, and do brakes, the oldest son opened up 2 transmission shops, and this is all from taking them under my wing, like my father and grandfather did me, their time and dedication, do it right, or don't do it at all, it was drilled in and by God it stuck, my little girl is 33 now, dad and paw-paw are gone now I sure do miss them, I think of them everyday, but it helps me concentrate on what I'm doing, I wish more people would do more to take time do more with the kids today, I turned out good, my kids turned out good, I'm sure yours turned out ok sorry I took so long writing, ill do better next time.
I love the classic small block Chevy. I've rebuilt them, installed performance parts on them and pushed them to the limits, great engine.
I have a .040 over 350 sbc in my 1971 Landcruiser that I built in 1994. Still runs strong.
Did same in 75 after I blew up the 6cyl
Avgass at airports 100 plus leaded octane cultivate your contacts gentlemen.oh and buy a 50 gal.tank for transport .
I had a 350 in my 71 blazer. I had to replace the camshaft sprocket when the plastic teeth came off. used a 57 cast iron gear and new chain. sold the rusted out truck with almost 200k on it. engine never burned a lot of oil or had any compression problems. it ran and ran. I have owned a 265, two 283s, 307,305, and 327. all gave good service. love your video
I've had several 350 all through the 60's and 70's .
Very good engines .
Nick, the Chevrolet 350 I owned was a 350 Vortec V8 in a ‘97 Chevrolet K1500 pickup. When I was young my parents owned a 327 V8 in a ‘64 Chevrolet Impala two door sport coupe.
Always a treat when your newly built engine starts with a rear main seal leak.
Yeah when I was young and worked at a gas station ....small block Chevy engine was the most popular engine to be found under a hood of a vehicle to check motor oil... good content and thanks....🔧🔧👍
I had a 327. Loved that engine. Chevy small blocks of the pre smog era were very good at making power. I'm a Mopar guy but i really respect small block Chevy's.
you could really make those 327's spin. Great engine!
I had a 327 in a 1968 Camaro. I'm also a Mopar guy and had a 1971 Charger, 440 six-pack at the same time, as well. Love those small block Chevys. ❤
383 was Dodge's best engine.
I like the videos produced because it is professionally done by both George and Nick. The dyno is a great tool to find out many facts about the engine . Nick and Phil, good to see you both, great production George and team.
I have 355 cid in my truck 412 cid 768 HP in my S10 drag race truck 9:10/ 156 mph / My sons 388 cid in a 3 gen Camaro my other street strip car 1979 Chevy Monza, Spyder 396 sbc four-speed 9” ford 10:01 quarter-mile past fun car I build engines for a living love watching Nick garage !!!
owned & ran 2 SBC for years. Ran 1969 SS Camaro, 350 +.030, LT-1 solid lifter cam on the street to play with. also ran a 1967 Camaro w/ 327 2bbl, auto (power glide)on the strip every weekend during the summer in the SS/PA class.
There was also a 307. I have had 4 350's. All have had over 200K on them. My Suburban had 417,000 miles and still ran great, the body just rusted away. Drove it to the bone yard.
Phil it's good to see you.. I always enjoy your added intellect with Nicks.. You guys make a great team.. this always brings me back to the old days of the 60's and 70's.. But you take it to the next step we never really could.. Carry on boys! and thanks.
Thanks for watching.
@@nickpanaritis4122 purely my pleasure..
Nick, back in the day I went to the GM Powertrain plant in Tonawanda, New York. The 350s were on small carts going through the assembly process. I remember the big billboard telling every shift how many they made. Thanks Nick!
Got a 1928 Olds with a 72 lt 1 350 B&M 173 supercharger. It's been on the road since 1986 in this configuration. In the family since 1982.
I’m not a Chevy guy but I don’t mind their old small blocks. Simple and easy to work on, parts are cheap and plentiful. They’re not power monsters but they’re adequate and super reliable with just a little bit of maintenance.
Awesome video love Nick's garage God bless you all❤ when you unplugged the vacuum advance, total went down to Mechanical minus the vac, in the distributor which is probably total of 19 minus the 12 to 15 vac adv because you had it at 34 if you had a 21 to 24 degree bushing in the distributor . with the vacuum unplug the vacuum set your total and then plug the vacuum back in especially for the street. So initial time it must have been like around 2 to 4° initial, that's why it popped through the carburetor
350SBC in my 91 C1500. 325,000 miles and still runs great. Oil changes every 3000 miles using wix filters. Napa Gold is a rebranded wix. Last year I finally had to replace the distributor when the plastics in the hall sensor broke up. Easy to replace distributor and reset timing. Still running strong. Can`t beat the longevity of a well maintained 350.
An owner operator that I worked with got over a million miles on the 350 in his 3/4 ton van. He showed his loyalty by replacing it with a Nissan. Ingrate!
Thanks Nick an your brother Phil and of course George for his awesome camera work.....
Old F-4 Phantom ll pilot Shoe🇺🇸
That music in the background is just at the right level to almost not be discernible and actually sounds like an engine problem when it's idling.
Nick congratulations you're one great engine builder I specialize in Chevy small block 350 I love Chevrolet that was my first car 72 Camaro keep up the good work
You inspire me to do something productive everyday Nick. All my dad did was watch Gunsmoke on television and tinker with lawnmowers. I say tinker because none of them ever ran again. HA!
Greetings from Adelaide Australia. Soon to be from the United Kingdom. On vacation flying out today
Hope you enjoy it!
Don't believe the news ...the UK isn't that bad 👌🇬🇧🇬🇧🇬🇧🇬🇧 here
I have a 1994 Chevrolet Silverado 1500 with the 5.7 ltr(350 cu in) in it. Bought the truck new and she's still running with 430,000 kms on her. All original.
The Small Block Chevy was Gods gift to the internal combustion engine. I love all cars but the SBC has a big part of my heart. And the most cost effective.
these lil sbc respond to just about anything. my first car was 69 malibu 2dr coupe motor sticker say 350/300hp 4sp muncie. man do i miss it. this was fantastic thank you nick camera man and the engine doner. me and a 69 roadrunner 383 mag. every single night goin at it. funnest cheap thrills a 16 year old could ever have, you guy no,,
Before the actual dyno pulls, I'm going to guess it will make 325 hp. Always great the knowledge you have to share in your years of being a mechanic along with your videos. Always appreciated.
Love the videos with your brother, 2 great minds working together 👍
I’m so glad it didn’t get Nick but when that thing backfarted and scared Nick I laughed so hard! 🤣 I’ve had that exact same thing happen so many times when tuning those things.
Awesome show Nick and crew had some 350 Chevys over the year each one acted differently good all a round engine keep them coming and see you Monday
Yup! Had a 350 in my 72 Chevy Blazer. Used to change the oil and filter on the 1st of every month. Retired the Blazer at 272,000 miles and the engine was running strong.
Change your oil once a month I hope you drove a lot
I have owned them all. I will take the 400 crank and the 350 block. Best combo out there. Us Pontiac guys know that combo was great in the 389 days. That 3.750 stroke is a sweet street set up.
I had a 70 1/2 Camaro RS in the mid to late 80's with a professionally built 350 with 11:1 compression, crower cam, holley 750 vacuum secondaies, holley street dominator intake, head work, was a beast, paired with a muncie rock crusher and 3:73 gears.
a thing to remember about small block chevys . always check the camshaft bore it should have equal meat all around the cam bearing bore if its not it isnt a square casting and for everything it responds well to it will respond even worse to if its off !
Great video Nick .. some of the mysteries are now solved .. love your Dyno .. great work testing the engine .. nice street engine once the leak is fixed .,
Thanks 👍
Hi Nick, I probably have had about 6 of the 350 at least. Also had a couple 307 and a 327. All were great engines and basically trouble-free. Was nice to see a small block Chevy for a change, thanks Nick and George. Cant wait to see your 6 banger on the dyno!
Dana "60" Glass. Small block Chevrolet started was introduced in June 1954 for the 1955 model year as a 265 cubic inch. Standard 2bbl, and the 4bbl "Hot One". In 1956 the advertisement went, "The Hot One gets even hotter." '57 grew to the 283, first to reach one horsepower per cubic inch with fuel injection. '62 the 327, '67 the 350, '70 the 400. Probably the most versatile V8 motor ever created. Used in passenger cars, pickup trucks, boats, and medium duty trucks just to name a few uses. The one on the dyno ran pretty well. Hopefully the owner will let you shim the valve springs or replace them. Valve springs will only get weaker. Great job as always.
Thanks Dana!
Nick is the Einstein of the automotive world
No 350, but had a 60-over, de-stroked 327 with crane roller cam/kit, 13:1 pistons (240 compression). It held it's own against 500 BBCs on the dirt track.
A destroked 327 ? Wouldn't that be a 302 ?
@@outinthesticks1035 Remember that it was punched 60. I think it came out to 317--and it was a beast.
Another top video Nick & George, I'm sure after chatting with client you will get it sorted and it will be one sweet 350. Have a great week Nick & all.
Thanks 👍
I had a small block 400 that was poked and stroked had an Edelbrock medium rise dual carb single plane manifold had Mallory electronic ignition and a set of shorty headers out to glasspacks I had it in a 60 Chevrolet truck with the granny box 4-speed with a gear vendors Overdrive.. you could put it in first gear rev it up to about 4 grand and pop the clutch and it would pull the front wheels off the ground it would smoke the tires in second gear for a month and would pass everything but a gas station pretty fast Fleetside truck ask me about the one ton panel van that I had that I had a V12 GMC dump truck engine in😮
Yep, had a 350 in my 70 Camaro SS/RS and a 327 in my 68 Camaro SS. Both ran long and strong.
Great seeing your versatility Nick and that like my vocational teacher in automotive school said.
All manufactures back in the day designed, and made dependable, reliable power plants.
Each engine from all the manufacturers had a specific type of use. Weather it be a reliable all around daily transportation. Or a performance muscle car motor. I graduated from automotive school in 1971. Before I went to automotive school.
I was 15 years old worked a summer job in an auto salvage yard in Allentown Pa in the late 60's. When not working I played around in my neighborhood with local hot rods, and short circle track stock cars.
My first engine my brother and I rebuilt was a 283 Chevrolet. Great first engine to learn on. Very forgiving for a youth to practice with.
I worked in the automotive field for thirty plus years. Served in US Army for twenty five of those working on wheel and tracked vehicles. Worked for Chrysler in dealships for about 16 years. Owned a bunch of Mopars too.
I like the old Mopars personality. Own a 1984 Z/28 I plan on building some day. My daily drivers are Fords which I must admit are more reliable, then my Dodges were. Again old Mopar's were some of the best...
Great video Nick love all of them and I am a big fan of your's.
Sincerely Arni
Had many 350 & 305 engines no problems with them good engines ! Good video!
Mr.Nick, GM has made some good engines, I've run in-line 6 250, 283, 327, and several 350's no problems or complaints, and a Dodge 318, now the Chevy SB has a rear main oil leak problem if you seat them right and put a dab of sealant, they will leak, glad to see you run a Chevy on your dyno,good video see you next time.
Hello from Indianapolis, Indiana. Just a couple of miles from the track. Watching at lunch time. I love the Dyno tests. Great job Nick! You have your hands tied with no information on the SB 350. But you will pull the most HP and Torque out of it. Another awesome video. Shawn.
Right on!
Rebuilt 1 350 from a 1970 Impala. Could not get the distributor in time but someone else did finally. Had more ponies under the hood than it did.
Not GM fan, yet surely a fan of Nick!
Nice engine, thanks for sharing, all the best to you and your loved ones
After it is leak free etc , I hope we see a final dyno run ! Thanks again Nick and team . ✌
NICK'S GARAGE NUMBER ONE ALWAYS 👌
I built my first 350 this past winter. Ported the heads (370 castings) and the Edelbrock RPM intake. Check out the dyno pulls on staninoshawa. Great work, as always, Nick!
Hey guys, from Pittsburgh!! I owned a 1974 Z28 camaro once that was 350 powered. I bought it as an automatic, but later converted it to a 4 speed. I think this one will produce at least one horse per cube.
I'm from Indiana county Pennsylvania...
SBC always my goto. Currently running an 85 Monte 350, 20 over, Elgin flat tappet, with 700R4 into Dana 60 373 gear.
Built many from mild to kinda wild….one of my favorite smells…. Burning header paint… the last few I built had lifters that oiled the cam lobes directly. I now run big blocks exclusively.
Our British Rover V8'S share the same design Taken good care of they last a really long time At Nick's Garage you can make sure you're V8 is doing fine Nick can hook it up to his dyno and break a cam in Only then can the testing begin Every Monday it's Nick's Garage for the win Thanks Nick and George
Rover pushrod V8s are based on the Buick 215 V8 which have little in common with Chevy smallblocks. It started out as a 3.5 liter and I believe ended up at 4.9. It was the basis for the Buick V6 which was one of the best engines that GM ever built. But back in the day each division of GM had their own engine design team and there was not a lot of crossover between divisions.
@@richardfehr1838 Thanks for the education Next time I speak about a Rover V8 It wont be a foot in mouth situation
- Well you were correct in that they are all OHV designs... with minor differences...
The Buick 215 first appeared about 1950 and still in after market Rover version production as far as I know...
I had a 1971 Chevy 350 Camaro best dam engine ever made!
I went car shopping in 1971 as a young man looking for his first new car. The Dodge Challenger at the Dodge dealer on had a 318 and automatic. The Chevy dealer had a Camaro with a 350 and a 4-speed for less money (just over $3,500 sticker) so that’s what I bought. I also had a truck with a 350 3-speed 4:11 posi and a 327 and a 400 small block in other vehicles. I lived in northern Wisconsin and most new vehicles were basically strippers. My first four car’s didn’t even have a radio!
Well said. Go Chevy, it's cheap.
I had three of them ,loved them all
Another GREAT DYNO TEST/TUNE day!
The engine may have had a mild rebuild. But without knowing, it's guessing in the dark. Still, it does have good torque.
Maybe he will want Nick to put some H.P. parts in it. That would be great!
Thanks Nick for the DYNO Day!
Engine looks over cammed for the heads flow...
Hey Nick, back in the early 80s i owned a 1973 Chev Monte Carlo, 350 sb, great handling big car! only had a 500cfm 2-barrel carb.
Owned many 350s,couple 400s, a 307 and several big block 396s.
Some 396's were actually 402's and their owners didn't know.
I had a 350 in my 3/4 ton pickup in high school. It was a '74, so low compression. With Holley 650 spreadbore, Edelbrock 2101 manifold and Crower cam as the only mods, the truck had 100k miles on it and would run low 16's in the 1/4.
I have a 11.5/1 355 that runs forged rods on a 4 bolt crank with a comp cams 280 H roller rockers and performer rpm intake with a 3310-1 Holley that I run in my 55. Just ran 17 passes on it this weekend and ran 13s every pass with 80 percent of those with a passenger. Best pass 13.16 at 103. Drove it to Blue Suede Cruise and back both days and never touched the engine.
Nice!!!
Only had 2 small block Chebbys. A 265 that I put into a 52 chevy pick-em-up. A 350 that I put into an 83 Malibu wagon. Had lots of trouble with the 350. It was a roller tappet engine and a couple of the tappets were noisy on cold startup, replace them. Also had a main bearing problem that required an align bore to solve. The mains looked good during assembly, crank rotated free enough but it developed a slight main knock. They built millions of the things but compared to the small block MoPars they are a little on the flimsy side. Crank & rods are much lighter on the 350, even the truck engines.
I had a 350 4 barrel in a 1972 Buick Skylark, it would do a smoke show all the way down the street.
Awsome. Thanks for the memory.
Chevrolet or Buick 350 distributor in the front or rear
Chevrolet distributor at the rear. Buick distributor at the front. There is no mistaking one for the other.
Totally different engines... Buick vs Chevy... only interchangeable part would be the carburetor...
Not a bad little street engine. My last 355 SBC made 340 HP and 390 TQ with warmed over 882 Cast truck heads, and a dual pattern comp cam. 9.0-1 compression. Performer intake and 650 carb. 25 degrees initial timing, 35 total.
I just put a 350 Corvette in my 81 Elcamino. Came out of 91 Vette. My 80 Olds Cutlass has a 406 3.80 stroke 4.125 bore. Built by Sending Performance in Texas u.s.a.
Owned numerous SBC. 307-358 and buit several more 307-400.
Here in Oz GMH got 307s as the first V8 Holden. I have owned several, both powerslide and 4 speed. Then we got a couple of thousand 327 250hp with 4 speed for our 'Bathurst' special Monaros which won
Had several 350 Monaros of later models and specs. All autos. Best one was modded and had around 370hp and 6500 useable revs. Rest were stock and a couple gutless slugs.
Roadraced a Torana XU1 which started with a Webered 6 and then went Chev and ended up with just over 500whp.12-1, Victor Race heads, solid roller cam. In a 920kg car it kept you awake!
New carbies come within the ball park of what is required, The more efficient the intake and heads will change jet size. I would lean it up one or two jet numbers.
Though as you say it seems weak in the springs
That small block Chevy cranked up before Nick hit the startup button. Hard to beat the small block Chevy.
I’ve got a 68 impala with 327 and my dad has a 99 suburban with 350 so between the two of us we have the first and last year of the “big journal” small block chevys 😁 we both daily drive them.
Indeed, I have had many variants. That setup you're running is the most dependable and cheapest install matched with that HEI distributor. ✌️😎
You made me laugh at the end when mentioned about the oil leak 100 times 😂
Best engine for street racing. I have built many of them for that. Also built a small block 400.
I see a Nick rebuild brewing. I had a 427 that was so messed up it blew up twice. It turned out that it couldn't hold a line bore--but it could hold paint.
I only use Howard camshafts now in a Flat tappet Cam.
Only one I haven't lost a camshaft on.
Had 3 Corvettes,75 Silverado, and a 93 Roadmaster with the 350. The Roadmaster was my favorite road vehicle.
yeah got a 350 in bits one time i was going to rebuild it but swapped it for 2 351 clevo's i guess he just wanted it more plus fords to me are like dodges to you, thanks mate and g'day to the team
1976 Caprice had a 350, 4 bbl Rochester. Trouble free. A few SBC in 68 Impala. 307 (garbage) changed to 327 (strong, ended up in my buddies 1967 Firebird, it had the OHC in it, we took it to the dump) 81 Monte Carlo with the anemic 4.4 litre.
Nick your brother Phil is a very smart guy and I can tell he's a great tuner
funny thought nick as you said that was the second engine i worked on when i first started as a young kid. a 261 in a 1959 chevy c-60 rack truck and a 1962 305 gmc v-6. those were the days. then i stuck with the 318 and 440s better yet. dyno time it will scream im sure!
I really like your videos. Very relatable to see you going through the motions, minus the dyno. My adrenaline is usually going the whole time. I'm surprised people get away with stock springs with a bigger cam. Ive never gotten so lucky, and i always opt for the matching spring package.
Hi Nick Had a 350 in my 1989 Bayliner, yes they put them in boats as well lol
I had a 327 with a 4 speed in a 1963 Impala in high school (1972). I bought it for $300.
Best engines ever. I have a 406 SBC that makes 540 hp and 550 tq. that purs like a kitten on the street.
Its my favorite go to utility engine. I've put 370,000 278,000 300,000 miles on three of my Suburbans and pickup over the years. Secret? Oil and filter changes @8,000 miles. Kind below zero cold starts,no over revs and keeping it cool in Summer. That's my story... Lol
I have my g-pas 85 Suburban with a 454cid with around 525,000 miles on it...! Maintenance makes a huge difference...!!!
@@kurtisstutzman7056 I had a Chevy pickup with the same engine and if it didn't break in half from the rust I'd still be driving it! Lousy NY salted roads ruin vehicles. Luckily it didn't break in half driving it. I was loading it on a trailer and it folded between the bed and cab.
@rickdaystar477 Born and raised in Florida, and I'm so glad there's no salt down here...!
Blows me away people are still risking it all and going with the flat tappet
I have been lucky with Mopars with flat tappet cams. Done many .
Hydraulic flat tappet cam and lifters $250.00 USD. Roller cam kit $1256.00 USD. That's why
I have those same valve covers on my gm 290 crate. Going to ditch those soon when I move to a roller cam setup and afr heads and intake.
* Me thinks Nick is a :
*"Closet Chevy~Man!♡¡"*
Had a 69 GTO with an oil leak from the very front of the oil pan. It was almost just as bad as the one on this 350. I tightened the oil pan bolts in the front and significantly reduced the leak, but everyday I noticed 1, or two drops on my driveway. That's a serious pet peeve of mine and really causes my OCD to act up! Lol. The valve float is definitely on the engine builder and that's not acceptable. Whoever did this job wasn't doing it thoroughly at all. The oil leak is the least of the problems compared to valve float because of paying poor attention to important details while assembling the engine. That 350 has some good numbers for a good daily driver with some get up and go depending on the vehicle it's being installed into and the rest of the setup. If I was the owner of this engine and have the financial means I would have an experienced mechanic like Nick do the repairs. To be fare maybe the original engine builder made a couple of mistakes, or he had an employee do the job. Who knows, but that video was interesting to watch and see what troubleshooting methods were used. 👍👍
Evenin Mr George an Mr Nick! Have a Great week!!
Thanks, you too! Take care.
Hi from Hungary Nicks.Your videos are very good
Glad you like them! Thanks for watching in Hungary.
Great chance to show viewers the relation between ignition timing at idle, engine manifold vacuum at idle and engine idle smoothness (and RPM). Nick could show viewers how to use a vacuum gauge to set engine air fuel mixture (C0) at idle and how best idle smoothness (when going for best manifold vacuum reading) results in a higher CO reading. Usually higher than allowed CO. I will offer to give the demo Nick if you fly me out there. I already have winter clothes as I live in Northern Idaho.
This engine most likely has a decent cam and some porting work and the larger 2.02 valve heads, along with a set of forged pistons. 330hp is not bad at all.
I would like to see those secondary ignition waveforms at that rpm point where the dyno shows a problem. An engine "O scope" would be a perfect fit for Nick's dyno room. A Sun distributor machine so as to verify the advance curve would also fit in nice. These are simple old school performance tools. A tuned points style distributor and performance coil would be an asset here.
