LS3 Vette gains 67rwhp, 40rwtq with cam, LS7 exhaust, bolt-ons
A user on the Corvette forum wanted a real clean, stealthy setup, without the hassles of headers. He swapped the LS3 exhaust manifolds/exhaust for LS7 manifolds/exhaust, then added:
Custom Comp Cam, spec'd by Patrick G 218/230 .563/.573 on 115lsa +0, Comp XE lobes
PAC beehive springs, comp titanium retainers, comp 7.425 pushrods
Cometic .040 head gaskets for 11:1 static compression
LS7 Exhaust Manifolds with Cat Pipes
Dr Gas 3" X-pipe
ATI 10% underdrive pulley
Yella Terra roller rockers

That thing looks like it could have pulled a couple hundred more RPM as well, nice.

damn, i wouldn't have expected a cam of that size on a 115 lsa to hold peak power like that...nice.
i assume having no advance contributed to this?
nice numbers, badass setup on manifolds.

Stock NVH and stock drivability, but with LS7 power is pretty attractive. Not everyone wants a loud, rough, unrefined road rocket.

When people go from 440 rwhp to 500 rwhp with bolt-ons, is most of that gain coming from the tune? Just trying to figure it out.
