It was okay but really lackluster in performance, that 7:6:1 400 just didn’t have enough compression to be happy with that cam. I used it because I was strapped for cash and already had it on the shelf, thinking back the 066 cam that the factory originally used in that engine would have performed much better.
If you’re set on running the 2801 I’d advise cutting the heads for compression or better yet swap them for a set of ‘68 -‘70 350 heads after converting to screw in studs. It’s going to be hard to cut those 6X-4 heads enough to raise your compression by on point.
The 2800 is a far better fit for your engine as it sits.

Ok so the 2800 would be a better fit for the engine as it sits, and as Steve said it would also be ok with the stock valve springs. Would this 2800 pick up a decent amount of power and give it a better idle sound too? I’m just trying to figure out if it is or isn’t basically like the stock cam that’s in it.
