How much power can a LS3 block handle? I wana put tfs245 with n20 port by btr and btr cam. 105Mm Holley hi ran with 2in headers 13:1cr on e85 should I to solid roller or stay hydraulic with short travel lifters. I wana spray 300-350 on this setup. And is their a iron block 6.0 that will to 4.070 bore safe?

I wouldnt get too greedy with nitrous on that application. The main issue is with a 427 on a small bore you end up running a 4.125 crank and the result is a thinner crown on the piston.

I was gona use the 4.100 crank

Its still limiting the crown of the piston. I wouldnt run over a 4" stroke on a short deck block personally.

I wana know how much I can hit it with lol

Id limit it to a 200 shot personally. Past that your putting alot of heat on a thin piston.
