You need a few more pens in your pocket Pat...lol
I think they started breeding.
I was coming down to say the same thing!
Frankie needs a mess of pens like boss man...
Half of em are mini screwdrivers
He keeps loosing his pens and grabs another one but doesn’t realize he just keeps putting them in his pocket lol
Its the little details like "Time for Torque and Jet for horsepower" that make this channel so wholesome
So by "Jet for horsepower" you mean, buying $7500 worth of race carburetors and testing for optimum horsepower?
@@Anarchy-Is-Liberty ya exactly… how come you don’t have 5 carbs just for your Chevy 305
So you pick and choose, so what
@@boywhohasl1vedhascometodie469 why don’t you have 5 carbs on hand ?
@@rustypotatos I do not know, why don't you make an educated guess for the carburetor with the data presented through the video? Aint that hard.
I've gotta say it, the faces Pat makes when dogs of an engine are on the dyno are WAY more entertaining than any high dollar build they've done...
Underdog appreciations
It’s more fun tbh
You know money will make power so meh
Go watch his nitrous stance he take on the ls budget build video.🤣
It's the same maniacal look he uses watching Frankie.
Hints of updog.
Man, used to watching these programs Sundays at 7-9am through the 90's, along with shadetree mechanics on Cable. Just now found this channel... Crazy.
Me too man haha
What cave have you been living in. This show never stopped.
I want to go live in that cave so I can be that removed from society too. Lol
Me too!
You got some catching up to do my man lol
Back when it was good info without all the commercials and ads....
So far this is my favorite episode you have done. Testing engine theory is so important in today's information age. There is so much hearsay online and oftentimes no data to back it up. Episodes like this are invaluable. I cannot wait to see more tests on a higher horsepower motor.
Yet again, engines are individuals that can fail in different places, like my 15’ Subaru WRX has gone 90,000 miles with no major engine issues, and meanwhile some have had the rear mainseal blow on them for no apparent reason.
I'm an older guy who started out tuning with points type distributors. It's entertaining and useful to watch you guys methodically tune and experiment with the 305. I've watch you guys play with dozens of engines over the years and enjoy each episode. I also learn some little bit every time. Thanks!
Hey guys I appreciate this ALOT. I went the computer route and didn't learn engines and motors until way later and it was just simple little tiny things like oil and spark plugs. This here taught me A LOT especially the other videos on breaking down and entire engine, cleaning it and rebuilding it so I can see details on how it's all assembled and how it all works. Many thanks again. I'm 39 and got into this a little late in life, but UA-cam and y'all's channel is helping me to get caught up!
Ladies, get you a man that looks at you like Pat looks at Torque curves
or a woman
You need to be politically correct.
@@basshead. "People, get you a person..."
Curves are curves 😎
Dont forget the extraterrestrials. They have feelings too. Honestly.

I’m glad Pat mentioned the balancer slipping as it’s a common problem on old engines. That’s a little grunt for for a 305!
It made 20hp less, gross through headers than LB9s got up to, net.
Great content and breakdown of every change. This is real-world type stuff here!
The 305 in my 1979 Chevy Malibu was starved for air when it left the factory. I upgraded to a less-restrictive filter and that helped. Out of warranty, I switched to a pure synthetic oil but switched again to a natural/synthetic blend to keep oil pressure up a bit. The only thing I did after that was move to a slightly warmer spark plug and I indexed them in each cylinder. I picked up, overall, maybe 22 horsepower and I felt I'd done a pretty good job for a very low cost.
When I first came across this episode I was interested then intrigued and finally impressed, this video is outstanding!
Now you need to go through different spark plugs styles and heat ranges.
One of the Gems on UA-cam, i think so many myths busted. Thanks much for the efforts
Thanks guys this was a wonderful illustration of maximizing performance. The clearly legible stats at the end was the cherry on the top. Happy motoring.
You guys have one of the best and most relevant HP testing channels out there. Keep up the great work.
Great Episode! This type of comparison really illustrates things I've tried for years on a variety of junkers without knowing if my perception of improvement equaled reality! Lol.
I learn so much from this part of power nation I love making engines go faster!!!!
All the presentations are good but this one might be the most useful for the masses - thanks POWERNATION.
Thank You for doing something with the 305, so many of us guys are still running the mini mouse with no little to no feedback from the aftermarket.
it's an SBC. Many SBC parts are interchangeable. Just keep in mind some 305's that came out of Mexico were prone to cracking. So you can't go too crazy trying to make power. But you should be able to get away with mild cam, good intake manifold, smaller combustion chamber heads, headers, and a 750-850 cfm carb.
@@ericinMN1970Yes, SBC stuff bolts onto the 305. But, the first gen 305 is hamstrung by it's small bore, maxed out (intake, carb, heads, exhaust), they would make 325HP. No way would you invest that time and money into an underperforming engine. Normal bolt-ons won't generate as much power on the 305 as it would on even a 307 due to bore size (and potentially larger valves). Free (or cheap bolt on) power is a great way to enjoy the 5.0 while saving for your 350 swap.
Engine Masters turbocharged a 305 made good power. That is what you need to do.
@@dj4monie I’m going to do the right (wrong) thing and drop a mild cam into my 305 powered Firebird... because it has a Th700R4 ahead of a 9 bolt one wheel peal, both of which max out around 300HP rating. The car is too original to cut up and modify heavily, so I’m boxing up everything that comes off and installing period correct upgrades. It may never make 300 HP, but it will appeal to everyone who remembers the 80s.
L31 vortec cylinder heads are a great close to 50 horsepower addition (need to be shaved 0.03"-0.04") mild cam swaps are good,keep lift under 0.460-0.480" ,headers are good with a free flowing exhaust
Pats hair reminds me of a set of long tube headers with flames shooting out the ends
Lol right on
Good stuff, I definitely appreciated the oil viscosity test.
Pat is the only reason I still watch this channel.
Great Video
I am in the process of restoring my 1985 Pontiac Firebird that I purchased new when I was 19 years old.
It has a 305 4barrel quadrajet carb.
I have been thinking of changing to fuel injection.
Thanks again guys !!!
Mike
Is Mike galley gone ?.....Lotta years, well thanks for the entertainment and best of luck 👍
Keep doing tests on this like using different intakes with the various carbs you just used such as dual plane , single plane , single plane high rise , etc., etc., please . It should be good for a couple of more shows worth of content .
Try watching motor trend engine masters. They have several side by side comparison test along the lines you mentioned.
Yeah this was a good video, I liked seeing how it different parts effect the dyno numbers
That would be very cool. However I'd like to see things like a Peformer vs EPS vs RPM vs Torker vs Torker II vs Victor on a common 400+ HP 350 and how they are in the low and mid range. Yes they've done similar tests but I believe on 383s and 406s in the 500+ horse range. Maybe Torker and Torker II would be more in the running on the milder combo (they did horrible on the higher strung engines.)
I’ve literally been watching you guys since you were on tv on the weekends, of course I’ll subscribe.
Excellent demonstration of component changes and timing changes
Literally the same shit they do in every episode.
Good video for bolt on upgrades. I would have liked to see the carbs tuned after each initial run though.
This test was very interesting, I hope you guys do MORE of this.
I would love for you to set a degree wheel on there so you know exactly where the top dead center is on how far off the balancer Mark was.
Other than that very good demo.
If my balancer is off that far, it's a good bet I'm buying a new one!!
It would be "doggy" with a stock converter and high gears.
Wow so i have a 79 z28 170 hp stock so by advancing the timing n and a carburetor like the second one u guys put makes such a big difference thank u 🙏
Great video guys. Really good information for the people that are new to hot rodding.
Yep, videos you can't stop watching are the best! 😁
Not against the new guy, but a goodbye from mike would have been nice..
I don't think it was Mikes decision. I think Powernation doesn't allow it.
Out of all the host changes over the years, I think the only one that was acknowledged by powernation was when Joe Elmore stepped into the background. Other than him I can’t think of another host that didn’t simply disappear...
Whatever the case, I'm just one of the 768k+ subscribers that think it's no big deal. Mike may not have wanted to say anything. Pretty sure no one here knows. I hope Frankie does a good job. I'm sure he's got a dream job.
I’ve been here since the show aired on tv
N I’m 20 now
That was an interesting experiment, Thanks Gentlemen!
You can tell you guys have gasoline in your blood. The knowledge is amazing.
My father was like this. I grew up in a garage, 3 bay garage. Just being around him at the garage and listening over the decades has a massive amount of knowledge. He showed me as much as I wanted to learn. God rest his soul.
Keep them videos coming these test are cool. Let's do some intercooler testing vs no intercooler & e85 vs 91unleaded .iridium vs regular or test some octane boosters
Loving that "slick-back mullet" pat keep rockin it bro makes you look more of a rebel
skullet
This has really helped me with a starting point for my 85 C-10. It has the original 305 in it & I want to get a little more power before I decide if I’m going to do an LS Swap or not.
Do borh
Cool episode. Definitely need another one with a 500-700hp engine.
The stock air cleaner setup made a bigger difference than is shown looking just at peak numbers. The extra restriction really came into play at the very top end of the range when airflow demand was highest. The ram air style filter might have had a positive impact on a moving vehicle.
A difference would have been noticed between stock exhaust and headers.
Perhaps not on low hp engine. I saw another vid on UA-cam and on low hp stock engine (iirc a low comp reman 350 making around 250hp with rams horns) and headers made hardly any difference at all believe it or not.
Then they put roller rockers on - almost no difference again.
On some engines roller rockers make an improvement, particularly inline 6 Jeep engines pick up 15 hp and of course you need them on any engine if your gonna rev it up, but the point was on a stock SBC they make no difference.
I saw them test headers on a miata and they only gained .5 hp. It did sound way better
Shoulda started with logs
Those were not stock exhaust that were used.
Not on a 305 that makes peak 182 hp at 4200 rpm
Great video with good information!! Liked, Subscribed, can’t wait for the next one!
Yes do more testing on carbs and intake plenums and air cleaners!! Like carb hats with air cleaners, high profile and low profile ect ect! Small hole factory air cleaner assembly vs bigger and compared to open element!
You know Pat is a real mechanic because along with his pens, there's a tread depth gauge in his pocket. I bet he's got a spark plug gap gauge on his keyring too..
Love what you guys are doing here. I started working in my grandfathers shop when I was 3, and long before I started putting power adders on engines, grandpa and my dad spent a lot of time teaching me about timing and fuel delivery. Anyone can bolt on new heads, but the real skill with engine building comes from tuning. This is what the next generation of engine builders need to understand, and it's awesome that you're taking the time to explain the ins and outs of basic tuning.. Maybe you could do an episode showing the gains we can get from the old school hot rodding tricks; like plug indexing, off-set wristpin bushings, rod balancing, plug wire shielding/grounding, etc...
Don't forget the half missing mullet too!!
I'd love to see you guys do a comparison between synthetic and non-synthetic oils. Specifically like Penzoil vs Royal Purple. Maybe get one of them to sponsor it.
I absolutely love this channel.
I love this channel so much keep up the amazing work !!!
Could you do a dyno study on setting timing by using a vacuum gauge instead of a timing light. It would be interesting to see if peak vacuum numbers under load correspond with peck power.
This has to be done!
Ya ..I dident even know you could set timing using only vacuums ..I will look this up .. thanks
Actually it would be lowest vacuum gives highest power... but you also have to consider too big a carb. gives poor drivability at lower RPMs...
You can only do that accurately if it uses points though. Also as they stated you time for torque and jet for HP.
My point was that since an engine is basically just a big pump for air I bet Max vacuum would give you the greatest throttle response off of the primary's. But not necessarily the greatest horsepower. When the secondary blades are wide open. So it would be cool to see on a dyno how much power difference there is between max horsepower at correct timing. and timing at max vacuum as in a nice smooth daily driver setup. Wich one would give better mileage also.
I'd be interested to see what difference spark plugs / HT leads / coil could make.
I suspect not much, but would be interested to see.
Cool little test!
The young guy reminds me of the dudes who come out of college and think they know it all, when they really have much to learn. Nice video! Learned something new today
Check out "Project Farm's" test of those free-flowing air filters before you put one on your engine.
I watched that one. I would like to see them replace the K&N with a dry high flow filter like Airaid or AEM
@@RFXLR do you think there would be much difference?
@@LilasTools I’m not sure but I’m thinking those dry filters would have a tighter weave because they’re not relying on oil in their filters.
Thanks for the videos, I’d never pay extra to that other company
That.. fellows, was a very informative session.
Thank you.
love the channel guys ! keep it up!
Oil choice also effects engine lubrication on startup. Thick oil takes longer to get moving from a cold start which causes more engine wear. Thin oil is better for cold starts but reduces oil pressure when hot which may increase engine wear.
New cars have tighter tolerances and can use thinner oil. I would not use either extreme in my car.
I'm getting engine masters vibes.
This is a great show for Young Beginners
101👍's up thanks again for taking the time for us all to be with you
The evac actually was making relatively the same peak power but at a significantly lower RPM. You should consider that.
Wondering about PCV systems recirculating air and fresh air ones myself.
Why not find TDC and then Mark the balancer so you know if the balancer is correct
You do have mark on the engine for TDC and on the balancer wheel, but the challenge is that is only every second time the piston is in top that there is a spark. The engine is 4 stroke. Therefore you need to find the TDC with compression.
Put ya finger in the spark plug hole when it blows ya finger away turn till the balancer lines up BANG TDC 😎
Watch running mate to find tdc . Exhaust intake both open evenly is running mate tdc
I mark my own like that anyway
Stock tend to not be accurate or go far enough
Still one of my favorite, thanks guys
Wish I could get Pat to help me do my Supercharged 4.0l Cologne. LOL
Just watching that guy do his thing is always a lot of fun.
Had two 305's in my day. Both were garbage. That was a great engine to test on because if those improvements worked on the lowly 305, they will work on anything.
Throw a set of 350 heads on it from the junkyard and punch out the cylinders about .40 over and you'll have a 350 give or take a few cubic inches. Those old chevy small blocks interchanged parts except pistons
The young kid couldn't be more robotic
Facts bro !!!!
Great video to show comparisons. Would like to have seen it started with a dual-plane to show what the little 305 is capable of.
I learned a lot! Thank you!
I would have used a piston stop when you had the plug out to find true TDC on the balancer . Only, of course, if it wasn’t actively slipping.
Slipping? How does it do that? On a keyway from the crank?
I choose a 305 engine in my 74 camaro for daily driving, using a 350 or even a 383 was asking for horrid gas mileage and overheating on our hot summer days in crowded freeways like the 405 and 101. The 305 shines especially on long freeway drives where low ET's dont matter, is reliable and smooth, and has plenty of real world power when it counts, in town and on freeway on ramps. All these different carbs do of course make bigger horsepower gains but only come in a wide open throttle, how would they do in off idle throttle response? gas mileage? Holley carbs have a tendency to leak fuel and need alot of attention to keep running plus they will foul plugs and what about their mileage at a steady state cruise? Anyway, for real world in town and freeway cruising, I abandoned holleys decades ago, went to AFB's and found the best throttle response came from the smallest carb they make on my 305 their 500 com afb. Using a combo of 273 gears and tall tires my heavy camaro gets 26 mpg at 60 mph and 2000 rpm. Your best real world gains come from ignition tuning, get a good HEI dizzy, find your best plugs (almost always AC 45 tsx) and pay strict attention to your wires, then jet lean. Now you have a smooth daily driver thats easy on the wallet, get good mileage and is silly reliable, besides being a joy to drive.
I have an ‘89 Sierra with a 350 TBI, 700R4 and 3.42:1 gears. 23 MPG highway and never overheated in traffic, even in Texas.
@@yaboileeroy3038 thats a good set up, thankfully you are not in calif and so dont have to deal with the retarded fuel prices here along with all the restrictive laws they put on you out here. I also have an 84 Silverado with the 700r4 and they make my 350 motor drink easy on the gas, something like 21 mpg on the freeway. greetings from the peoples republic!
Great video, something with content we all can relate to.
Great video. I learned something from that
Didn't taking that fan off add horsepower right there? Pat
I agree, it would have been cool to see a pull done with the fan in place and then removed to see what the difference would be!
LOL yep, but unless you put an electric water pump/fan on, you won't have that added horsepower for long LOL
Usually about 3 to 12 hp gain depending on the type of fan and the engine used
Somebody told me I'd get 30hp changing to electric fan in my GMC Sierra 5.3l... even for 10hp that's cheap hp...
@@ofursteini. I think it would be closer to the 10hp gain and I agree, that's definitely worth it. Clutch fans don't draw much when they're not engaged. But when one of those are stuck locked, they're the worst out of em all and probably would draw 30! HP.
What was the A/F ratio?
I just started watching this channel today, but this honestly needs to be a TV show.
It is. Their stuff has been around for about 20 yrs
Totally cool tests,like the oil runs.
Pat, I think you need a couple more pens for that pocket protector... LOL
Watch out for that horse pressure
That was awesome, great video!
THANK YOU SO MUCH!!!! SOMETHING TO CONSIDER!!!!
Missed the obvious "lid flip" on the stock air filter.
On my truck, I doubled the air cleaner cause I had room!
Yeah back in the day that added BIG power! Well, not so much...But we did it anyway! 😁
@@danf4616
Engine Masters did it and gained 6 HP on the dyno. The biggest HP killer is a flex fan - 12 HP!! Worse even yet is most guys don't run a shroud with them, making it completely ineffective. So it robs HP, and your ride overheats. Brilliant!!🙄😂
Did the lid flip on my Chevy during the summertime, needed the carb heat during the winter. Did not see anyone mention the "quadrajet moan" here so added my 2 cents!!!

LOVE this video, so real world. Made a great evening lol
Amazing video guys👍
How you can evaluate carb changes with out mentioning air fuel ratio . And doing jet changes is misleading .
I was going to comment on that. Want to see the A/F between carbs and why no 600/650 4V?
Engine masters get deep into that, go check them out

The first thing you do is a compression check to see if you have an engine.
AIR, FUEL, COMPRESSION, SPARK is what i was taught, ya oil for lube... WTF !
@@hallz9117 Without compression, air, fuel and spark are irrelevant.
@@highwaymen1237 2+2=5 .. new skool shit
Compression is Especially useful for Diesel, it’s how it runs 🤦♂️
Should have added the E3 plugs test...
Probably because it would have made no difference, or E3 didn't offer enough 💰💰💰💰
The most important thing I used to do on the small blocks is to adjust the valves close to zero clearance quarter turn down that makes horsepower and RPM and of course play with the distributor and plugs for the right heat range and a new set of wires is key keeper engine happy
Best sounding 305 I've ever heard. I underestimated that little engine
Back in the 80s we would flip the top over on our stock air cleaners to make more noise lol
the original open air filter :)
Would love to see yall build this engine up and then do all the exact same tests

Very interesting and useful information
