Performer rpm or M-1 intake
Now that the comparing arguments are taking place, just what is this car used for? IMO, even with 4.10's and that purple shaft, I'd do a RPM-AG without a doubt, as someone mentioned, (LOL) Been there done that got the T shirt!
The M-1 can be a hell of a performer, but I'd leave it off in the street on a 360 with that cam and combo.
