Hello, I have a 2006 C6 with a LS2 6.0. Looking to do a cam swap. Picked up a LS7 camshaft, 1.8 rockers and a Brian Tooley spring kit. Just wondering if anyone on the boards tried a LS7 camshaft and how it performed? Can't wait till I get a break from work so I can install the kit and get it tuned...
For all the work and effort to do a cam swap, I would not put a factory LS7 cam into a 6.0 with cathedral heads
It will deliver POOR results! (maybe with LS3 heads).
I would look hard at the Cam Motion LS1/2 Titan 4 227*/232* 113* +4* .612"/.595" (with 1.7 rockers).
You will pick up ~50 hp and still be very street friendly with a good tune.
Not sure if you can run 1.8 rockers designed for rectangle port heads on cathedrals either.
Just my .02
Yeah, that cam is going to be way soft down low without the extra 60+ cubic inches that the LS7 sports. Your stock cam will probably out pull it below 5000 rpm.
Cam specs are
211 intake
230 exhaust
.591 lift intake and exhaust with 1.8 ratio rockers. It's actually a small cam. I have to pass emissions so I'm running a Ca legal cam. The 6.0 has plenty of compression so it should have plenty of cylinder psi. I'll do a cranking compression test before and after the cam change. I'll also post Dyno numbers. I'm as also going to run the Z06 exhaust system. Z06 has the best flowing manifolds. Just a fun project. Fun car.. Looking better
Thats a lot of work to throw a factory ls7 cam in an ls2 for minimal if not negative results. Hell it won't even sound like you cammed it so really no gain to be had. Buy a proper spec cam for your motor from BTR, Texas Speed, Cam Motion, or GPI
The lift and duration are fine on the LS7 cam. The deal killer is with the 121 degree lobe separation angle. That shifts the power band WAY to the right while killing low and mid range power. The small gains above 5500 rpm aren't worth killing power in an RPM band that you actually use on the streets. How often are you above 5500 rpm on the streets?
Something hidden from view (like a camshaft) isn't going to fail you at test time as long as the tune is stock and your Vette passes the sniffer (if it has to be sniffed). Your MSD intake manifold will fail you though. There's absolutely no value in running any other Chevrolet cam. When you move from a stock LS2 cam, you have technically failed the test. I'm sure there are folks running mild aftermarket cams that pass. Cams that are much more well rounded than the LS7 cam.
2006 C6 6.0 cam question...
