Just wondering a stock block 6.0 from a 3/4 ton truck cast block what hp rating is it good to? also how about the crank? Ive heard 800rwhp? thanks

 

[Novaflash2002]

1200 hp for both. but at 800rwhp it will live a long time

Yeah and don't try 9000rpm on the stock bottom, it will break a rod bolt before it gets there!

Now 8000rpm especially with some ARPs is money

Tirefryins10 makes a tick over 1100 rwhp on a stock unfilled lq4 block and crank. Stock 317 head castings as well. Twin 76mm iirc turbo combo at 20 psi. Stock computer, harness, and coils too.

will hit my 6.0 with a 91,5mm turbo, arp head and rodbolts and some mls gaskets, before I go all the way with diffferent rods, pistons, crank, heads etc.. Will be interesting.. :smt073

i know this is a change in subject but what about the 5.3 crank and block. are they comparable limit wise?????

They seem to take a hell of a beating.... cylinder walls are really thick
