Need cam help

Hi I have a 13k miles ls3 out of a camaro, anyways it's going in a 93 rx7 with a t56 trans an z06 clutch. The car weighs 2700lbs with engine and I was looking at the gm asa cam out of the 525hp ls3 crate engine. What's your thoughts? And do I need to get springs and retainers?
Thanks
Richard

Any of the GM cams are complete junk. Call BTR and have him help you select a cam, or have Pat G spec a custom grind out.

Almost any aftermarket cam will need springs, retainers, seals, pushrods, etc.

What kind of power adder do you have to make 650 at tires with hot cam

Don't use a GM cam.

I agree with Unreal. Patrick Guerra ("Pat G"), Brian Tooley Racing (BTR), Vengeance Racing, and many many others out there can help get you a cam.

No way an LS3 is making 650 RWHP NA with any cam. Only way that's happening is a blower or nitrous.

Is it going to be a carbed setup? Hell, with a manual and that kind of weight, I would personally consider one of the new low-lash solid lifter grinds. But with that, you would have to lift the heads to change the lifters, which it would be beneficial to do anyhow, imho. With a solid roller you could really spin that thing to make serious power in the upper rpms and probably make more torque to boot.

GM doesn't make a 2,600 lbs. car and non of the over the counter cams are grind for a car that light.

Yeah I would love to do a blower but I do not have a ton of room for a blower, I would need a lower profile lsa lid to make it work or something that is not much taller than stock ls intake.
