Im in the process of rebuilding my motor. I can't make up my mind about a cam choice. I was running a Cam Motion CM-1 cam in my motor. A 12.1 451 with indy 440-1 heads, in a full street trim 70 GTX. The CM-1 was a little too much for street driving, so im thinking a little something tamer. I was looking at the R-1 Cam that specs out at 272/276@.50 with 620 lift comapred to the Cm-1 cam that has 276/283 @.50 with 691/630 lift.

This isnt a car that i drive on the street all the time, I drive it from time too time, and race it every so often. Guess what im asking has anybody run the R-1 , and does it have decent street manners. Im just pulling my hair out trying to pick a cam.
