Went back to naturally aspirated due to a new love for autocrossing and for now, I'm staying with the stock cube ls3 crate motor.
I sent the heads out to Frankenstein heads for their stage 1 head porting. I added a Spinmonster cam and ended up with 497 rwhp and 447 rwtq.

I wanted a cam with very good driving manors and I was not disappointed [230 234 114+2]. I has only 4 degrees of overlap and drives very close to stock. Look up the Spinmonster cam in the corvette forum for more details. I also added the Comp Cams trunion kit and had the intake ported by Peak speed shop.

Drivetrain is a Magnum T56 with a Moser 12 bolt with 3:70 gears...18/12 Forgelines.

This just shows you can get great power with a mild cam and a great set of heads, nothing earth shattering, just a good setup with great power.

Can't wait to hit the track!!!

Pretty good numbers. Maybe get an ATI pully, FAST intake and you'll be 500 to the wheels.

I'm happy with it for now. The next plan is a 416 with a Cammotion LLSR and a Holley hi rise shortened and ported by Chris Frank [Frankenstein heads].

I want it to spin to close to 8000 so I don't have to shift to second gear!!!

If I may ask was it supercharged?

not this time, but before I had a Maggie on top with a LS9 cam making about 680 rwhp.

I am looking at putting a Magnacharger on my LS3. I am only getting around 450HP RWHP with my Texas Speed crate engine. Is there a disadvantage with supercharging?

Nice numbers Matt! Your next upgrade will easily break 600rwhp......8000 rpm!!!! Let me know when you have time, I would love a drive with the new setup.
