Lt1 block + boost How much horsepower can the LT1 block handle ? Callies crank , Lunati rods, diamond pistons , splayed caps, arp head studs , arp rod bolts, AFR 227 heads with a gt47-88mm turbo . I know im ok with the internals , just wondering on how much the block can take before cracking .

i would save the money for an lsx block. a 427 maybe ? you get 6 bolt heads witch will prevent quite a bit of head lifting issues. and he block is proven to make over 2000whp.

With the Lt1 block head lifting wont be the problem we have 5 bolts per cylinder and you can make good power without having to go lsx.(even tho I wish I would have.lol)

yup i have seen 33psi with no issues and a buddy has seen just over 40 psi.... but the blocks strength and lt1 heads are an issue so,.. time for a dart block and much bigger heads...

Otherwhitemeat, do you think a half filled 355 would live a long time at 900-1000 rwhp? If not how much hp could you get out of it while keeping it alive for about four years?

It think 850ish rwhp might last a while...as long as there is zero detonation and your not into it too often.....bearings and rings wear out fast...i think the block flexes too much...

... I have seen premature main bearing wear and ring wear. BTW, I have seen videos of factory blocks on the dyno, under some special camera and lights...you can watch them flex....it pretty bad! I try to find a link.
