I love destoke 400s . Used to build them mid to late 80s till early 90s tunnel rammed with nitrous, supercharged and several single plane single carb ones with and without the gas. Such wonderful times kicking ass
I love them 377’s a little more than the 383 I’ll take that larger bore of a 377 over a 383 any day in race applications
,, ,, IN, # 6 2, - 3, !!, THE, LATE, MR, Z, " DUNTOV, " 👍, LIKED, THE, #377, , , "2," "4," THE, " GRAN, SPORTS, " !!,
Street also, over bore or over stroke is more efficient than squared engines initially.
The 377 makes a great dirt track engine built rite .
Use to run a 377 at the strip in a grimlin
I need this engine and a time machine. Unfinished business back in the late 60's while in high school.
Lol! I agree 100%. The competition would shit 😂😂😂

Love those 377 cid i built a 377 in the mid 90"s had wisco pistons 12.5 compression with childs albert aluminum rods with gm 041 heads
any idea what kind of hp you made?
My 377 pushed out 603 horsepower on dyno at 8500 rpm 546 foot pounds of torq a bad ass small block wished i had a set of racing heads and different intake
@@sportman8467 how ported were those 041 heads?
Actually we had alot of hours involved in porting work my dad was a smart man when it came to getting all the performance out gm production heads the crank was knife edged light weight 6" rods i think i bought crank rods pistons as a packaged deal gave 3k for them cam was a special grind my dad was responsible for it being ground i use to have spec card on it not sure if its lost or put up somewhere my father passed away in 2016 he was a man head of his time truly miss him
I had a 377 built in the early 90s for a street car I had.
The car was a 1987 Monte-Carlo ss the engine was one of the best engines I have owned when I sold the car I sold it with the engine which I regret doing to this day.
It was one of those engines that wasn't supposed to make the power that it did.
When I had it built I put the best parts in it that were available at the time.
I believe the best dyno pull was 753 horsepower with a signal carb.
I can't remember the exact RPMs I shifted the engine at but it was up there
To this day I regret selling the engine
On my 377 i couldn't afford the good heads so i use gm production 041 with 202 and 160 ported a little with small diameter base cam by comp cams put engine a 1970 ss nova full interior 3200 pounds with micky Thompson street tires i could only turn it 5800 to 6000 rpm and i ran 11.32 in the 1/4mile anyways never got to try on slicks ended up selling car but the 377 is the best engine I've ever had
Sounds like that was a fun car! Thanks for your reply Larry!
Very cool! I have a good 400 block and factory 350 steel crank. I'm planning to build a 377 for my 64 Vette. I'd be happy with just 500 hp though. It's just a street car.
Thanks Mark! The 377 combo is awesome. They like to rev! Good luck on your build. Thanks for watching👍👍👍
Nice I had a 377 in a 69 Camaro back in 86 much fun
Thanks for the content Looking forward to more videos! The mustang you built that showed at the world of wheels was bad ass. It was nice talking to you there. I’m the local ws6 Fbody guy that stopped at your shop this past summer
Eng- 399 Thanks, I appreciate that! Stop in anytime.
tell me the internals of the motor i have a 388 ci it makes 640hp
back in the late 90s my neighbor had a 67 camaro drag car with a 377 in it, made 700 HP. at 7200rpm running a 750cfm holly double pumper, he put it in a mud truck eventually, ran a LOT of passes with that motor. Ive wanted to build one every since.
Gotta few questions on self and timing i built 377 stroker
Fuel pressure and regulator?
I built a 406 back in 1988 with +.030 over trw flat top pistons .. still had a dish, 2.02 valve 64cc heads ( Had to use 93 octane from Amoco , Exxon or Chevron) Had a crane HMV278 cam .467 intake .494 exh lift and 222 or 224 intake @ .050 lift intake and 234 degrees exh. 114 deg lobe separation weiand dual plane intake with an old 800 thermoquad
It's amazing what one can do for cheap if they do their homework and mix and match the right parts combinations,,, one doesn't have to spend massive money to get massive results
That sounds bloody awesome
Thanks man! Stay tuned, I’m gonna post the video of the engine in the car tonight.
Real Good it'll definitely make 760hp , Billy says put some pair of 600 CFM carbs on it, I told him I don't know I think it just needs a little tuning on the 750 CFM 💯🚩
Built many mighty mouse engines... Shit doin 1 now. I like the 2 bolt over the 4. Beefier... Take advantage of the 6" rod angle relief. Doin an internal balanced 1 now, for a stick shift. Put a big Chevy snout on crank .milidon caps...
Cool show!
Like your performance I build two destroke 400 with 327 camshaft man nasty sbc build another 400 283 crankshaft using comp Solis roller camshaft love 400 sbc you have nice set up
700 horsepower out of a naturally asperated 377 wow! Makes me want to do a 377 instead of a 383. I wonder how a 377 would do as a daily driver under 3,000 rpms
The 377 is an awesome engine but you have to spin them high RPM to make power. You would probably like a 383 better for a daily, because they have more torque down low where you would want it for daily driving. Thanks for checking out my vid👍
415 is the way to go...
735/522 out of a NA 377?!?! Holy guaca
That's nice that thing reved up to 8500 I gotta friend his turbo 400 let go on the bottle and reved his 377 to 12,500 that's what the tac was stuck and not the preset are on the tac to and that was on the bottle on launch
Thanks for your specs bro 😊
You got it my man! 👊👊👊
Jesus i see the sb2 exhaust ports. So those are some mean ass heads. And i bet thats a wicked camshaft in there. Thats badass. Im lookin to make 600 on my 509 block.
The heads are brodix 23 degree. The exhaust ports are stahl pattern not sb2. Thanks for checking out my videos!
Idk why i said sb2 lol. My bad on that one
Yes Bro your about right at the upper limits of the factory 400 block ...in fact I'm shocked you didn't opt for the RHS 400 casting or the SHP castings from any of the aftermarket guys the new designed 400 is just a much stronger starting point ..
Oh yeah, I just subscribed.👍
Right on👍 Thank you!
you need a O2 sensor on each header runner to jet each corner of the carbs ,then you should gain the power you hope for .
You are correct. We tuned it bank to bank on the dyno, there is still more power to be had. Didn’t want to push it any farther.
@@FFRC i trust it isn't hurt, but what an exciting way to test a great combination with that intake:o)
8000+ rpm's......i saw that Aaron.
Quality original 400 block would make a real nasty 421
Sweet build! Very impressive for a factory block!
What was done to the bottom end to keep the crank from spitting out on the ground? Did you install splayed caps or any sort of girdle to keep that thing in one piece?
I seen some pretty horrific carnage of sbc factory 2 bolt 400 blocks that the main caps let loose and spit the crank on the ground. 😳
My next build on my channel is a factory block sbc 400 stroker to 434 cid. It has splayed main caps and a halo girdle, hoping that will be enough for the Dart Pro-1 CNC 227 23 degree heads? Also has a Howard's 4-7 swap solid roller cam. I don't think it'll have the HP your has but it will possibly be more torque?
Going to be keeping my fingers crossed that the crank stays in the block. Hope to hear what you did to keep that from happening. Thanks in advance.
Thanks I appreciate it! I still used the stock main caps but I used ARP studs and made a girdle/windage tray all one piece. worked out perfect. Its been holding up good, Ive been beating the hell out of it LOL!
@@aaronstapleton8104
Very cool, is it a 2 or 4 bolt main?
Fingers crossed that mine will hold up.🤞
@@itseithergonnaworkoritaint7852 Its a 4 bolt main.
I've heard that the two bolt blocks are a little stronger than the 4 bolt on the 400 due to the design or lack of material for the two extra bolts idk but it's what I've heard what's your opinion?
That is amazing power for gen 1 N/A beast
Really nice work. Time to put it all into a dart or motown block, And save it all from destruction. hahahhah lol.
👍
I bought a 55 chevy cameo a few years back and it has a mildly built 377. The guy I got it from told me not to rev it over 4500rpm. Does that sound right? I’d love to message over the build list I have for it to see what you think if you ever had the time! Thank you!
No problem, send it over to crew@fastforwardracecars.com
You must have the 350 block standard bore with 4 crank depending on build should only go up to 5500 to 6000rpm to be safe supposedly...
Thanks for the video. I have been kicking around building a 377. Right now i have a 406, i do not believe i will be happy with. The motor is going into a 79 su bird H body, like a monza.
I have a steel 350 crank , that came out of a modified dirt car motor. It is .020 undersize, needs a good polishing. I have stock 5.565 rods with forged .030 pistons on them. I have 2 sets of heads to use, i have anberaly set of pro comp heads, never been run, and i have a set of 461, that have some serious bowl porting and porting done to them. Those headscwent 10.99 on a 406 in a 78 malibu. Dual plane air gap intake. Reason i dont beleive i would be happy with the 406 in my sunbird. Way to much torque for my little car, do t want to twist it.
Your thoughts ?
I raced in a restricted superstocks dirt track division. 363cid chevy max rule. Holley 500cfm 2bl carb. We put 327 crank in 400. Yes it cubed to 348cid. We gave up 15 cubes but on flipside revved it 7200rpm (flat tappet cam, 10.5 max compression rule, iron heads with no porting allowed). It ate the competion.
Nice👍
Happy motor Happy life the wife will get over it
I'm impressed the horse power , is that a stock block if so wut year ??
Thanks! Yes stock block 1970.
@@FFRC I have a couple of 400 blocks and I always wanted to build a 377 but not to sure of the bearing spacers .
I'm working on a 66 Nova as well.
Sounds to me cam is 680 + need that to turn them rpms. I have a 380 which is the 400 block with 3.50 stroke not 3.48. I have a 700 solid roller iron eagle heads worked. But dont know what power it may bring. What do you think. Oh 13.5 compression
I have a dz302 block billet crank forged piston forged h-beam rods. Studs an girdles top an bottom... how long has your engine lived? All my bearings were shot (doing rebuild now)
You think with 12° heads could have done better or ? Track and street engine ?
Forsure. These are 23 deg heads. If we used all pro 12deg. It would definitely make more power.
I been wanting to build a 377 for a while now. Is there anything special that I need to do to the Block or crank to run a 350 crank in a 400? What rods would I need and is there a wrist pin offset? Can I turn it up 10grand All Day, like a 350? Lol... thanks for any input or suggestions.
He told one guy here in the comments that he used 6" rods.
It's like a 350 but instead of .060 over pistons, it's .125 over, so as long as the bit of extra piston weight doesn't tear the rod caps off, it's fine. Also they use bearing spacers for the crank. It looks like two bearings stacked
Very cool build I'm doing a 406 now and have a second block with a 1970 forged crank to put it at 377 I'm just wondering what kind of power I'll be making I'm almost at my first start any day on the 406. That's a really cool build .an love those old school valve covers. I found a plain set of Edelbrock chrome valve covers with a nice old school air cleaner to match. Looks like a 327 i had in 1984 in high school. Anyway I've got alot of questions more than i could ask tonight but as far as bottom end what rods are you using for that rpm it's running and you briefly mentioned the crank. Just curious cause I'm clueless to what kind of power I'm gonna be making. 218 cc heads 205 160 flow 302 at 650 n start falling a little still good at 7. Cam is solid roller 639 654 exhaust 265ish duration. 800 cfm carb . Is there a formula to figure this out. Sorry so long you're the first video with a 377 like i want to do that's old school. All i hear is it's the wrong thing to do but from the sounds of yours that thing is badass. Can't wait to see it in your nova . Thanks for taking the time to make that video that made my day. Have a good one!
I have 379 destroked 400 too, vortec heads stock , i plan for 234 /254 273 /292 114 .377 .389 solid roller cam. What is the quench, and the cam duration that work for you?
The quench was set at .039 and the duration is 286/297@.050
What parts do you have in motor? Specs, heads,cam, low end ??
What compression is in this engine. I also have a 377 stock block. It a 3.50 stroke crank with 6in rods 630 solid roller dart 215 iron eagles. Wondering what kinda power. It's 13.1 pistons
what heads are you running on this combination
My hubby is working on a 377 right now ! Wants to know specs. Did not get to see 1st. Vid.
Hi I have 377 but only makes 500hp. If its not top secret what are the cam specs and compression ratio and fuel. Thanks.

What crank?? Gm steel or aftermarket..did you plug the water passage on the block,,filled with hardblock stuff ??..splayed cap ??..you can help us here man..thanks
I have the same heads with Alot of port work and bigger valves than they came with...question is what compression ratio and carb u had when it was single carb....also was it race or e 85 or...
I’m wondering the sane
What length rods does it take and pistons I have a dart 400 block im wanting to destroke but don't know what I needs besides 3.48 crank???
6” long
I'm a little late to the party here, but I am building one myself. what did you do to the main caps to hold the horsepower and rpm?
I never seen a n/a small block make that much hp will have to wait to see a parts list head flow # and cam specs i don't believe it yet not saying impossible but just never seen one especially a streetable one let us know your specs
What’s all been done to the motor? I have a 400 currently and I’m very interested in this build!
Everything lol! The heads and intake were ported in house. We spent a lot time getting them right.
Are those Brodix -10 heads?
what brodix heads and cam are you running,, solid roller
Do you or do you know anyone in your area who does good work with Modular fords like the ones in a new edge mustang? I looked you up and I drive a Truck for a living and have been all around where you guys are located. I need to also locate a good 2000 - 2004 mustang to start i have an 01 GT but it will be my driver. Ill sell my 2015 explorer when I start the project.
question, your cam was hyd or solid roller?
Solid roller
Could you upload you build sheet? So I can build a similar motor
Did you add steam holes to the heads?
What crank and rods and pistons and spec on heads
That is what I want to know.
tell me about the camshaft
Traditional 23 degree heads??
Can you tell me more bout the internals and the heads
What’s in the bottom end and how much do you charge to go threw a block
Smh !! Parts laying around ! Really 377ci/700hp is nothing short of full blown race engine, or at very least some seriously expensive cylinder heads, most probably couldn't afford to have laying around 😂 but wicked motor none the less.
What spacers did you use for the crank ?
I used the King Bearing spacers.
Wat cam are you running im building a single 4 barrel for my 95 s10
What's the compression ratio and cam specs?
What's comp ratio can spec and head spec thanks
I have a 377 with vic Jr 64cc heads are they good for my engine
What was done for block prep have a 400 thinking about something similar but efi thanks
We bored and honed it. Squared the decks, align honed the mains and opened up the lifter bores to .904. Thanks for watching!
The heck with the dyno, what are the specs.
Do you use 6.0in rods??
What block number ?
I am boosting a Sbc 400 40 over 5.7 rod
All forged 817 block shooting for 600 wheel hp but was a little nervous with the stock block I did hear of guys making more so fingers crossed lol
The block I used was a 1970 511 block. These blocks are definitely not ideal for boost lol. But it’s like anything, if you take it easy on the boost it may live for awhile. Good luck on your build and thanks for checking out my video👍
@@FFRC haha! We are definitely gonna test that theory haha!!
Thanks for the reply I appreciate it ..
600 wheel will be over 700 crank. I have a 406 forged crank,rods,pistons, solid roller Erson cam(.548 .548 ) 1.6 rockers make it a .584, AFR 210 comp heads(65cc chambers) victor jr intake, FST billet extreme 750 carb and 17/8 headers and I made 526/504 crank hp but only made 388 to the tires. Thought something was wrong but I guess that’s typical parasitic loss. Stock 511 block. Hope you don’t get your hopes up because dyno’s smash them. Take care and always mark your territory with 2 black marks.
@@royalchaser8090 oh wow ! You definitely have more motor then me! Sounds like you went on the mustang dyno aka the heartbreaker people call them lol because it sounds to me like 385 is very low …
But I am glad to hear the block is doing good!
My block is at the machine shop as we speak having it cleaned up and the decks machined for MLS gaskets . Lowering my compression down to 9.5ish for a more pump friendly for the turbo I’m not shooting for the moon I wanna try and squeeze into the 10’s
My turbo is capable of splitting the block in half that’s why I was thinking 500/600 to the wheel should get me there and would probably maxing out the block
Did you runs yours down the track yet ?
@@juiced71 I have ran probably 40 1/8 mile passes and I daily drive for 4 months a year and bust my car out on nice days in February if it’s not frozen outside. The best my Camaro has run with stock suspension and frame connectors is 1.64 60ft 7.46@92 mph on 92octane. It’s a dynojet that a friend owns for his shop. I have seen his 4 cylinder Toyota make 800 plus on the same rollers so I am not impressed with my numbers or the numbers that it cost to have built lol
I got a 306 I need some help with
Give us a call, we can help you out.
What is the compression on this engine?
Whats the specs on the cam and heads?????
Running on Methanol or Ethanol? Definitely not pump gas.
Is it a 400 with 350 crank it's fast if it's right
Yes sir.
That's hardly a street engine running on race gas.
SB2 heads, all high dollar stuff an average man can not afford ?!
Hey Peggy, Look close, the heads are not SB2 heads. They are 23 degree brodix. You can’t afford a stock block??? lol
I got my volume prank all the way I can't hear a goddamn thing hardly
Wat cam
What brodix heads
The heads are brodix 10x 23 degree
@@FFRC is any work done to the heads and how much u turning the motor rpm
@Bookie Williams The heads and intake manifold were hand ported in house. The engine makes peak power at 8000rpm. It can rev to 8500 rpm no problem.
What Top Plate is on that Victor Ram? Not the traditional Top Hat! Bitchen Build!
Thanks Daniel! It actually is the traditional victor ram top plate, but I did some trick porting and changed the design inside with epoxy.
😅😅😅😅
Afr 220's or 210's?
Neither, they are Brodix 10x
NO TORQUE USELESS HORSEPOWER
You're kidding right?
You must not know much about engines. Probably a junkyard LS guy.
It looks like you can't even spell your own name or your parents were mad at you.
I'm assuming you're just an ignorant troll.
