Good question, I have a Comp SI Torque Cam 214/220 .559/.564 111.5 lsp and I was told it would be good for a boost app, but I am not so sure...

I've heard the 02+ LS6 cam is nice for boost, but thats what I've heard..

Ive been told the zo6 cam was more of a higher rpm cam and to use something with more torque. What do you guys think?

The Lingenfelter GT2-3 is a 5.3 Radix favorite for allot of people. A Comp 212/218 would also be good IMO.

Any other sugestions or anyone with some dyno sheets with a vortec supercharger with different cams?

I may be mistaken, but doesn't the gt2-3 really benefit if you rev the engine out abit to say 6500. IF you want to leave the stock limiter at 6000 could you have more power with a different cam?

E.A.

It is a good cheap budget cam for F/I yes.

But all and all, if you spend about $100 more on a custom grind for your combo your going to be making more power in the long run. Plus lots of tuners stock their "custom" grinds so you don't have to wait for the delay most times.

Key word being "most"

Throw a late model LS1 Z06 cam in it. You can nit pik this to death. These cams are available for next to nothing or actually nothing if you're near a shop that works on a lot of vettes. If the high dollar cam has specs near the Z06 cam, chances are it will make similar power. I'm convinced that there's not much magic in cam selection. Look at the duration, lift, lsa, etc. My son has a Z06 cam in his Trick turboed truck. It's damn strong. Call me crazy, but I think a vortec supercharged truck is about like a belt driven turbocharged truck anyway. Cams ought to behave similarly.
