I dont see an LS4 making 500 NA whp, period. I'd love to be proven wrong, but I just dont see it happening.

Hmmm , i always figured the ct turbo kit would be easier , it is essentially a bolton , the problem is you have to cough up alot of dough up front. If i do go that route i would wanna do an ls6intake manifold first , ive been keeping my eyes open but i havent seen any yet.

That's good to know that other cranks can be machined for LS4 duty. I've not heard of anyone doing this, and I wonder why. I had always heard that our shorty crank was basically "it" for our motors, but I guess anything can be machined by a skilled shop and with the right amount of $$$.

It's definitely possible, especially in light of Ill_Born's info above. It just wouldn't be very streetable, as the power band would seriously move upstairs. You probably wouldn't want to drive it daily, though.
