Small Block & Big Block Chevy Specific - 400 Small Block Build Up ...

i just got a 1950 chevy truck and im doing everything over again on it i have a 400 small block chevy motor its stock and im going to run tunnel ram on it but so far thats all i have set as far as plans

ive built mototrs before but my goal is to get as close to 500 hp N/A out of this motor

no stroking and no bore

so what cam heads ect should i run :)

Is this a two or four bolt block hopefully its a 2 their stronger and you can still get it played to a 4, i would run a set of AFR's, what do you plan to do with this motor? Race, street, or street and strip???

the motor is going in a street/strip/show truck and id like to get into the 12s

its a 2 bolt main 400 small block everything is stock on it

it has dished pistons im not sure if that came stock but whatever

First off I would forget the tunnel ram idea . You can get that kind of HP out of a 400... but you are going to need some good heads. I would use AFR's. Also save your dollars for some good forged pistons. TRW's will work fine. Are you looking to use stock 5.565 or 5.7 rods? What type of compression and gas are you looking to run. What kind of cam(roller,flat tappet, solid,hyd), Carb and headers are budgeted.

AFR 210s, Super Vic, 850cfm mechanical secondary carb, 24x/24x .600/.600 solid roller, 10.5:1. You'll need a nice valvetrain and a decent bottom end but 500hp would be a given.

I have a set of 215cc dart heads on my 400 and like them.

AFR 225s, weiand intake, demon carb, 10.5 to 1 compression, and youd probably be close. ive seen a 383 make 541 HP N/A running that same setup.

:eek2: I knew he'd be putting out some power with that combo, but that much ??!!!! :eek2:

We just built one with the set up your looking for, stock crank, arp rod bolts, small solid roller 232-236 @.050 with .608 lift at the valve, both intake and exhaust. JE forged pistons, 11 to 1 C/R, AFR 227's, Vic Jr manifold, 850 cfm carb, 550 HP all day no worries.

If you have any questions give me a call.
