most stroke an lq4 to 408. You can go bigger like 434 but it's a lot more expensive.

What rotating assembly should I use on the 6.0, and heads and cams with a carb on it, to get 550-600 HP./ Also, what is recommended a 350 turbo or 400 turbo.? Again, I want to thank you for all answers, since I am new to this, I need all advice I can get. Thanks Again!!!

I think you have C.A.R.B (California Air Resources Board) mixed up with a carb (carburetor). The heads and come w/ C.A.R.B., not a carb. But it doesnt matter if it has a C.A.R.B. unless you live in smog Nazi Cali.

Well if you think you will be satisfied w/ 600 HP for a while you can pretty much order any stroker kit as the base/entry level ones are rated to usually rated to 700hp ish. Many vendors sell these for $1800ish w/ either Eagle or Callies products.

Either of the trannies will work fine, however a TH350 offers less parasitic driveline power loss and is lighter. Stock for stock the TH400 is stronger, but you can easily build the TH350 later down the road and still maintain the less power loss. You can't go wrong w/ either but if I had a choice between the 2 at same price Id prolly pick the 350.

Where did you get C.A.R.B. from?

He was talking about using a carburetor with the 6.0L and 243 heads.
