Go read up on the latest Car Craft Magazine, LS-power series. They just did a turbo on a 5.L 383 stroker and made 946HP/1006TQ. Also made a impressive 845/864 on 93 pump gas and meth.

How much HP/TQ you looking to make?

500-550 i plan to use the texas speed 11.0:1 compression balanced forged rotating assembly and their stage 2.5 heads and what ever cam they recommend. topping it with LT headers and high flow cats and a TBSS intake with a 90mm throttle body and a custom tune from Wheatley.

I think it would be wise to have your rotating assembly in hand so the machine shop can measure before they bore it.
But thats just me.
