And if so, what do you think of it. I'm going to be porting the heads, and doing a cam swap, and am considering the Hotcam, but I'm not sure if it's worth the $$$. I'd appreciate any comments from folks who have one in a ZZ4. BTW, it's in a 3300Lb 69 Chevelle, with a 2400 stall converter and 4.11's. I'm also looking to go with a single plane instead of the RPM that's on it now.
