Great vid fellas. Been lookin for a good small block build for a while now. Lifelong Small block guy here. Hope you have 1000 vids. Im ready to refresh my knowledge. Was deep in the SBC performance world, back in the 80's to about '95, then life happened, an now im back. Nice to refresh my skills a bit before diving back in the deep end. Please make more vids ; )
Question: I really like the meticulous measurements, what though do you do if you spend a lot of time and money machining the block and something is way out of spec. Maybe a machine shop error or whatever. Throw the block away? What would you do? Have you run into this before?
I'll answer what I would do: it depends on what's out of spec. The most important thing on 400's (any block really) are your cylinders. With engine blocks, you can sleeve cylinders if they're too far gone, but with 400's, the 4/6 and 5/7 cylinders are detrimental. They're Siamesed, and sleeving too far can cause head gasket issues since now the head bolts will have issues through torquing. If blocks are cracked, I've seen some fix the cracks through welding and small stuff, but most just scrap them. That's about all you can really do. It'll depend on whether or not it's worth saving. Id it's like a 409 W block, you'll do everything you can to save it. If it's a 400, not SOOOO much. If it's a 350, absolutely not. There's plenty around of those
awesome . what do you think about this? = 3.8" stroke 6" rods, dart 4.155" bore block, Dart cnc 227cc heads, 10.5:1 static compression, XR294HR10 hydraulic roller cam. 1978 Z28 with road race spoilers and fender wells filled with 17x7 P215 (50's ? )fronts, and 15x12 rear slot mag wheels with P325/60R15 or 50 series nitto nt555 street all season rear tires.
@@kingsleysmith2830 it wont rev past 5800 because you have edelbrock RPM heads. that makes total sense. theyre 185cc. you wanna rev this thing to 7000 or something? not a knock on your combo but thats what you built. about a 425HP small block street rod engine that'll run like a typical crate engine. the guy above? thats like a 550-560 HP engine because of those heads although he needs a solid roller with those AFR 227. a sorta destroked 400 is gonna wanna turn up.
with a 294HR cam i a almost 400 cubic inch destroked youd want smaller heads like a 210 AFR head and get a solid roller if you really want to utilize a 227 AFR head. thats a big head for a pump gas small block under 400 inches. people use those on 434s and make like 650+
You guys did a 377ci? I heard the part wheee he saido its got 350 mains. I built mine last year. Thats an awesome block you guys have there. People are skeptical about the bearing spacers (i used them), but i onow scat has a 3.500 inch stroke crank with 400 main journals on it. I love these builds. They never get enough credit.
@@mikeholguin84 the aftermarket block/crank have 2.450 mains (350) instead of standard 2.650 for factory 400sbc. smaller main journals have less friction and stronger because the caps are thicker. this is independent of stroke
@@Loswag888 ah ok. Yeah I don't know how I didn't think of that. Just like I wouldn't say I got a 3.48 crank or a 3.25 crank, lol. Id simply say a 350 or 327 crank. Dang man, smh, I should've thought a little harder lol
Guys in construction used to say, "You can't see it from my house." Very true, but I know if I did a shitty job of something or something just was kinda passable, but not right. My shit had to right.
Is it possible he could get his damn thumb off of the duration specs of the cam? I think mine is going to end up at 248/257 at .490 lift. Stock heads, rockers, and springs, hydraulic flat tappet, stock pistons, probably 8.5 to 1 compression ratio.
Bad news: thermal paper makes for horrible records. It just fades away after a few years. So when I have something I want a surer record of, I take the thermal printout and copy it using a laserjet style copier. But I must say that modern tech regarding hone quality brings a peace of mind to a build.

I'm so jealous of this kid, his dad and the environment his father has provided is so cool, the group of people to learn from is phenomenal!
Awesome video!!! Taking the time to do it right the first time will save you headaches in the future.
Now this is what I call proper engine building, lots of information, great video 💯💯💯👌🏽👌🏽👌🏽
Much appreciated 👌
So meticulous!! It's always a joy watching true craftsmen do their thing. Digging the custom engraved pistons too.
Thank you Jerrod!
I always check the cam at .020" and lash point also.
Craig is a true professional.
this gentleman certainly has a wealth of proper engine building skills …. 👍🏼
Thanks guys,great video!! I learned a lot!

Glad you’re enjoying them, thanks for following along👍
This should be a mean NA engine!
I spin the crank after I torque each cap. If you wait till your finished and there's a problem, you don't know which one is the problem.
What size piston rods did you use?
What clearances did you use on the mains, and rod bearings. Did you use the three hole dart cam bearings and how did you clock them?
Hi love your videos what are your cam specs doing a very similar build
How did you get a new block?

I’d put this up against any Big block or LS! This is a 12!
My LS is all ready for you.
@@johnziegler204 well not your Camaro! Lol
What Brand of Bearings is used.?

Sounds like a nice engine to me
How much hp and torque? I have the same cam in a 383 with edelbrock rpm heads and it won't rev past 5800
@@kingsleysmith2830 it wont rev past 5800 because you have edelbrock RPM heads. that makes total sense. theyre 185cc. you wanna rev this thing to 7000 or something?
not a knock on your combo but thats what you built. about a 425HP small block street rod engine that'll run like a typical crate engine.
the guy above? thats like a 550-560 HP engine because of those heads although he needs a solid roller with those AFR 227.
a sorta destroked 400 is gonna wanna turn up.
with a 294HR cam i a almost 400 cubic inch destroked youd want smaller heads like a 210 AFR head

@@KingJT80 Thanks, i am leaning toward Brodix 221cc now. Although want to go smaller. Going to 3.9" stroke for 423 c.i. And 10.75:1.
That motor probably would have made 30 ft lb more in the mid range on a tighter lsa.
Thanks for the input!

no it’s 400ci, the crank has 3.750 written on it

Could you make a video that shows me how to put together a small block??
Guys in construction used to say, "You can't see it from my house."
Very true, but I know if I did a shitty job of something or something just was kinda passable, but not right.
My shit had to right.
What is the part number for this 400
Zhp-0012

That was annoying, I think he was embarrassed that they chose a cam with such a wide lsa so he put his thumb over it.
good video, good job. You guys realize no vacuum advance will get bad gas mileage at part throttle! :(
Thank you. This engine definitely isn’t being built for gas mileage lol
so you learned that trick from yourself lmao died laughing
Can y’all build me a 400sb?

So who has had a comp cam degree incorrect and therefore returned it? Anyone? How about any other cam manufacturers? Anyone?
They must get paid per hour.
Who gets paid per hour?
You still want vaccum advance when you have to drive across town and want the best gas mileage, really!
Shame you restric the cubic inches.
