I blew the motor in my 01Z and going to do a rebuild. Wondering if I wanted to bore over the block what is the biggest a builder can safely go with a Stock LS6 block? Do any of the vendors sell a package I could purchase for my builder with all the parts ie crank, rods, pistons, seals, bearings, etc....

383. Just buy an ls2 block ang you can go up. Thats what i did. BUT,my boys 383ci makes 500hp to the ground and still on a non ported intake.

Is the 383 stroked or forged ? Looking to do this on a budget. 500RWHP with milled heads, cam, and porting is my goal.

383 is very popular then there is the 394ish 4.125 stroke

well it depends do you wana use the stock crank?

you can make 383 ci with the a stroker crank and the standard bore

a ls 383 using a ls1 block has a 4" stroke crank,most likely forged.you hone the block to 3.908.

383 ls1 3.905 bore 4 stroker crank, you can do a 393 LS1 3.905 with a 4.100 stroker crank. I think you can do a 400 not quite sure on the 400. The first two I know for sure can be done.

They make larger stroke cranks and correlating piston sets for that block so you could go 395ish cubic inches, but honestly if I was going to spend the extra money on a setup like that, I'd go with a different block and make it worth my time and effort!

383ci has been the long tested stand-by combo for that block, and works pretty well!

I have a 393ci stroker ('99 block, 4.100 stroke etc) that has 13k miles and makes 477rwhp/471rwtq...but these days you can do a newer gen style block w/ similar or less stroke and make 40+ more horsepower

At this point I am trying to determine from a cost perspective if its worth going with a 383 and using my block or just running a 402? I was trying to stay at about $4K for a long block but that is proving very tough quick.
