would like to know what kind of engine prep work youall are doing to support 900 hp to the wheels. here is my set up i have a 347 with lunti probillet rotating assembly and i have a t76gts kit with air to water intercooler.also have arp main studs, know the question is should i install billet main caps or the stock ones with arp studs are good enough.i'm also thinking off getting my block machined for 1/2 inch head studs, would like to know what you all are running and how much boost can you gat away with just regular arp head studs?

 

stock crank and mains good to at least 1000 rwhp

 

how about the heads??? will stock heads stay seated at these sort of levels??? or is it better to go with aftermarket anyway?? afterall they will flow better and the thicker deck should help! right???

thanks Chris.

 

you got it!

 

the heads?? they are fine?? but of course a thicker deck will benefit you??? and of course they will flow more???

 

sorry guys for acting dumb but i have seen some people making pretty cool numbers on stock heads! and it all adds cost to the project! right??? lol

thanks Chris.

 

I think:
-Stock main caps
-ARP main studs
-ARP or A1 head studs

1/2" head studs are for race cars. At that point you might as well o-ring the heads too.

You will spend a fair amount of money on your fuel system, and pcm controller before you find the limits of metric head studs.

 

thanks for the help.

 

I agree. You can make 900 rwhp on the ARP main and head studs. You may want to throw in a bottom end girdle for a little added insurance. Bob
