Cam sizing

What gears and converter do you have? Do you know your compression? Also you will need to change springs. I had a similar combo to what you are building. .484 cam and m1 intake. It sounded great but, wasnt very fast. Went with a smaller engle cam 216 at .050 int and ext. with .456 lift and 113 lc, and a 360 intake with the plenum milled. Car has stock converter 3.91 gears. went from a 15.05 at 88mph to 14.1 at 98mph I also picked up 5mpg.
