I have a cam out of a 350/330hp SBC crate motor that a fellow CK5er gave me a few years ago. It has very few miles on it and he even gave me the lifters. A friend told me today that it is the same cam as the ZZ4, but I have no idea if he is right or not. I was thinking of swapping the cam in my 92 Yukon, but if this will work good in there, I'm gonna go ahead and use it. What do you guys think?
