Cam Help

[toqwik]

I need some advice on choosing a cam.  Motor is a 383 .40 over, new double valve springs, heads milled .010, mild port job, with a cr around 11-1.  Car is a 68 coronet, auto tranny with a 355 sure grip.  Car is basically for some 1/4 mile fun.  It does have power brakes, and also what stall speed do I need to run.

.............U can go with a comp XE284H       part #21-2254 , because of ur compression, but u will need better valve springs...........2500 stall...........u may get away with a size smaller to b able to use ur springs, but u may run into detonation problems............kim........
