le1 le2 le3 ai185 ai200 ?
question is im looking for about 450 rwhp - current mods in sig = now where close.. so this brings me to a h/c swap and im wondering which i need to go with to get this kind of power... along with that i have now ill be getting bigger injectors bigger throttle body and porting the intake either by le or ai, also thinking about jumping up on displacement, so who makes a good 383 kit for the lt1 motor? preferably forged pistons anyways

I've heard good things about le, but i've opted to go with ai...http://advancedinduction.com/. I'm doing a 1200hp set-up, and ai will be doing the top-end...their h/c alone will get me at around 530-545 hp, and that's with around 8:1-8:5 comp.

both porters do top notch work. what you need to do is call and talk to both of them. i opted for lloyd and my car makes great power, but im looking to put the car in the 9's so its a toss up between the two for me also. time will tell.

You'll have excellent results with either one you choose.

450rwhp is possible even through a parasitic drivetrain, BUT is an unrealistic goal for an inexperianced builder/owner.
Cubes do not make HP, they can make HP more drivable but wont add it. HP is a function of airflow and everything above the block is what controls that.
I just have to shake my head when first it was a few guys hitting 400rwhp and then that became the standard and now more and more guys think 450 is just a matter of ordering a few part. These days 400rwhp is just a matter of the right parts and bolting it together right, 450rwhp is going to take a lot more knowledge and money at least to do it NA. You DO NOT need converted heads and a carbed intake as some would have you believe but it is still a lofty goal for most.

This is the reason I asked bout details of his setup. If he is running an LTX... no freaking way. I know a local guy who has a 8.5:1 408 LSX (with a single plane intake) and he made 440rwhp on motor and 860rwhp @14psi with a T88. The 440rwhp is approximately 520fwhp.
