Default What shortblock for a turbo project?

Well I have decided to go with a turbo for my ls1. I want to buy a forged shortblock for it but don't know what size to go with. Would a 383 stroker from texas-speed be good or should I go with something like a 370.

It all really depend on what kidna money u have to toss around. If u dont have much then get a forged LS1 with teh stock crank. If u have a litle more then get some aftermarket cast heads to help with teh pressure. If u ahve alot of money then get a 408 and good heads. It all really depends on what kidna money u have to sink into it all. They are all capable of making wayyyy to much power on race gas. On pump the bigger the engine the more power u will be able to get outta it with 93.
so figure otu how muchmoney u are willing to let go and go from there. GL man

well I just look at a forge Iron block 408. It was a around 4300 and the 383 stroker I was looking at was like 3400. I think I will just save up a little bit more and go witht the 408 since I just read the post about the 408 with stock heads putting down 920 RWHP. What type of heads should I go with and what cam also?

Since turbos are TQy i would just go with a 370. If it was a SC setup i would have said 402-408.
