Cam opinions 418

Thanks Earlie A!
It sounds like the rv2 uses a different bracket than the Sanderson, and although that is a huge compressor, it is probably not as deep as the Sanderson either.
I liked the bracket that junkyard linked to, and the shorty Sanderson compressor and will look into that.
Since the performer is just a copy of a factory 4 barrel manifold, did you notice a difference in your engine's performer when switching to the rpm air gap, and if so was it throughout the powerband? What size carburetor did you use for the new intake?

I know

My truck had been sitting for 10 years, had way too big a cam in it, had 7.7:1 compression and the 1970 manifold. I had the heads milled 0.080", ported the heads, changed the cam to a much smaller cam and installed the Air Gap with a 650 AVS2 all at the same time. It does run much better but still needs some tuning. I can't tell you how much difference the Air Gap made, but by looking and running my fingers through the manifolds I know it's a good bit better than the factory one.
