Back in 2003 I built a 400 2 bolt. Solid roller, lots of compression. A pair of pro topline 235 23* heads that I spent over 50 hours on. On my buddies new land and sea Dyno, it made 719 hp! Yes those heads were cast iron. And I ran a Edelbrock tunnel ram with a pair of 750 4150's
ALWAYS use a wire/coat hanger to get in the bottom of the water jackets. Sometimes there could be a couple inches of rusty crap down at the bottom of the cylinders. You'd be surprised how much comes out, if that's never been done.
My dad used to build 421 stokers for late model dirt cars 30 years ago made over 600hp. Last one he built back then still runs to this day. Nothing like sound of fast reving high hp sbc that can run dang near wide open for 100 laps straight. You got to grind out the block to clear those bolts for sure. Glad I am lucky enough to learn all this stuff hands on from him. I’m about to build a stroked 350 and I’ll be having to grind all of them 🤣
400’s were great motors to build for a dirt oval car. I want to say they would put 327 cranks in those blocks to shorten the stroke to handle that high RPM. I was going to build a 400 a few years ago. We had it in machine shop, but guy setting for a $3,000 engine that wouldn’t hold oil pressure. Now after 2 years of getting the motor fixed, he doesn’t want to race anymore.
@@mark4m557 the last 421 he built he had a custom 1 of a kind crankshaft made for it. If I remember correctly it weighed 39 pounds cost 15k! Lmao not his money his friends car. Might as well been family I learned to use riding mower in his yard shot my first pistol as well. RIP Charlie Martin
You guys ever worry about the crank getter by bent when it’s shipped to you? Think I’d have the machine shop check it for straightness when they balance the rotating sheet system.
With the 400 did u make all the oil and water holes are bigger than factory, and get a better water pump a low degree thermostat and high performance pil pump bc if not that thin is 100% gonna overheat or something man
If your building a flat top motor I've seen em hold up and I've seen some not ....it's 1 of those things were if u gonna do it go ahead and build it for it's intended use IMO
Reading some of the comments it appears some of you guys find it hard to believe this guy is getting 600 hp from his combo, as an example my 10.7 to 1 399ci SBC makes 641hp.@6400 on 89 octane fuel.
It must have some straight MONSTER heads and the perfect cam grind cuz most small blocks under 400ci are pressed to make even 550hp on pump gas. Not calling you a liar BUT I’d have to see it myself to believe it!
@@RealSteelStreet ; Have to admit I understand your doubt but it is what it is. I'm running Brodix 18* C-Series heads cut to 17* with 261cc runners that flow 404 cfm with a big block journal solid roller 260/266@.50 ..........679/668.......110. After talking to Bullet cams last week they came to the conclusion the nose weight on my springs are to light, They feel the cam should make power to 7000 with my combo so new springs will be put on soon, wonder what power increase I should see at 7000 vs 6400. Engine components for 7000 are a non issue......we always pray! lol
That is the shittiest 400 block to use. Use the 2 bolt "509" casting. The 4 bolt mains crack and hit water jackets due to different cooling passages. Speaking of cooling passages you didnt tap and then plug the 3 cooling passages on both decks and then after getting the block decked smooth drill out a 3/8th hole in said plugs. It will restrict coolant flow just a touch and keep the coolant in the block a bit longer drawing more heat out from the Siamese bores. Over drill the steam vents in the deck just a touch and do the same on the heads. Lastly. . .Ditch that crap block, it will die and take that crank with it when the webbing splits apart on the bottom end.
@@SSPENGINES383 what do u think about the 817 2 bolt blocks getting splayed and puttin the 4 bolt caps n it ?? I can't find a 4 bolt block, but I did run across a 817 2 bolt block last night. I'm thinking about trying it ????? Any advice would greatly appreciated !!!🙏
Amazing how many people are out there that think they know so much about building engines and people that dont know nothing either and pay one of these people not realizing they are paying someone who really dint know what the frig they are doing
@@jessesyfie7244 on 4 bolt 400s the outter bolts go into the webs in the casting. You're better off going with a 2 bolt main and converting it to a splayed 4 bolt main so it doesn't go into the casting webs like that. Not saying something will happen but better safe than sorry 350s and below aren't like that. Or just use ARP studs on a 2 bolt main 400 and not spin it high and stay safe at a 6500 RPM redline This is basically what they're alluding to.
@@KingJT80 ok. I was going do a 400 4 bolt built just for towing. IDLE TO 4200 RPM OR SO power band AND wanta use the 3 soft plug block 400. I shouldn't run into nothing with a 4 bolt stock setup I wouldn't think. It won't go over 4500 rpm maybe rarely over 4K.
@@jessesyfie7244 oh yeah that's an easy one. A cam two steps above stock like a comp cams Xtreme 4x4 cam like the smallest one in that series will do great. If you could get vortec heads and have the steam holes drilled and rocker studs pinned. Will pull stumps and idle very smoothly with lots of vaccum Get a matching Edelbrock vortec intake with a qjet carb. Can't go wrong with that combo

Man where are you located im in Georgia?
How much for you to build a engine like this?
Not surprised at all, wasn't no problem, 200 cc intake heads, .600 or over on cam, instant 600hp on about any well built 400
I need that motor for my malibu

Im currently inbetween buildimg a sbc 350 and sbc 400 whice would be better street set up , ?
Do aftermarket sbc blocks have this same problem with 6 inch H-beams and a big stroke?
No aftermarket blocks are already cut
Won't take too long till the three center main webs break free, if it's run hard.
what rods and pistons u useing

Looks like you kept the steam holes on your 400 .....they covered my steam holes at the machine shop I went to ....Is it bad to cover them up
Yes it will run hot most likely unless you put some money into the cooling system
that's the GM blocks you don't have to use them. They cool like garbage there's been better 400 blocks out for a long time.
