Sounds like the cam would have some bark, but no bite. Original poster please fix your signature, what are corrvet blocks and heavily worked chambers?

Um, no. Not with that duration and lift, or lack thereof.

That doesn't look like an LTx camshaft, and if it is it is the smallest camshaft I've ever seen anyone use in an LTx.

x2.

It's bigger than stock, but not by a whole lot. Seems like almost a waste to take the time to put that cam in, but maybe he had certain plans for the car.
