i would like to biuld a engine with a stock ctroke but a 4.00 bore. the reason i want to is because i will be using the L92/L76 package and throwing a turbo to it. does the 370 equal the 4.00 bore and a stock crank. also, can i do this with a LS1 or do i need a LS2 iron block. finally, will this be a good package to start with with a 76mm garret turbo intercooled at 18 psi max and 7-10 psi street use.

you must mean LS2 alum. block cause ive never seen an LS2 iron block, you can do it with either an LS2 block or a 6.0 iron block, i personally wouldnt go higher than a 370 with a 76mm, good luck on your build

Stock crank and 4" bore is 364 CU IN, you would need a 4.030 bore and stock stroke to achieve 370 CU IN. As for blocks either a LS1 Iron (LQ9) or a LS2 Aluminum have the 4" Bore.

i know the difference between the LS2 and the LQ9/LQ4 so sorry for the edit error. so to get a 370 i have to sacrifice one bore sesion on a brand new motor or just stay 364. can i get this with my stock LS1 and just resleeve it.

you can resleve an ls1 to a larger then 4" bore, i think they only do it around 4.1-4.16
it would probably be more cost effective to get an ls2 then to pay to get an ls1 relesleved if your trying to get to 4.0" to work with the l96 heads
