Im helping an old hot rodder with a 35 chevy. We are trying to get 400hp out of his 350ci. He has late model what I think are LT4 corvette heads. They are aluminum.

Head numbers:

10088113 - located near valve springs
3251 - located near valve springs

26131A - located on side of head

Are these heads capable of producing 400hp? Will they need port work to get there?

I also need help trying to find wich fuel injection setup to use.. he was gonna use some TPI setup but we were told if we go to radical of a cam we will have problems.

So basically I need help building a 400HP+ 355ci fuel injected motor for a 35 chevy. Thanks for any help.

Well he is what ive come up with so far...

Those heads will have to be ported as they only flow 196 cfm on intake side.. i found a guy who ported his and they flowed 260 cfm at .600 lift on the intake side and 188cfm at .600 lift on the exhuast side.. I found that the holley TPI is a good unit and some on this forum have suggested as the stock TPI runners are to long to make good power above 5,000 rpm. Im not sure what size Throttle body to use.. holley says use thier 2x58mm with that intake. Now what wiring harness do i get for this 35 chevy? I have read to use the 86-89 harness. As far as cam goes the one he has is just a stock chevy camaro cam wich is not gonna cut it.. i was told to use Comp Cams Grind 82 p/n 249-08-432-8 wich is good from 2200-5800 rpm. long tube headers of course with a free flowing exhuast system like dynomax or magnaflow. Will this make 400HP? Will this comb work?

What about using the whole MPFI system from holley wich includes everything I need to use fuel injection on an old car? Is this a good unit?

fuel injection??? wth? never heard of it..... no help here.......

not to get off topic, but have you checked out the SoCal rod shop in spring yet????

[crossfire84]

you could turbo city.com or jegs or summit racing these all sell good efi units, and as for the 400 hp not a problem a mild port job a good street roller and headers will put you way over this on pump gas, the z06 vette pumps out 405 hp. have fun

Z06 is a completely different monster.. From what ive read of the flow numbers of this head I can get 400HP but it will take a good amount of port work.. these heads are off an older style vette that is nothing like the LS1 motor of the new ones.

hey which TPI system are you using? the MAF (mass Air Flow) or SD (Speed Density) it dosent matter what car you get it out of but to be honest with you from pulling all of that out of one and doing it myself, I would go get one from painless wiring, I will hopefully taking all of mine out and redoing it this winter you run into too many small problems with using an old wiring harness, and most of all the whole thing is nearly plug n play once you have everything from the ECM to all the relays (those are included in a painless kit usually other than the ECM)
if you need to get more info on the TPI system go here www.thirdgen.org thats where I got most of my info on the TPI systems.
good luck hope this helps
