What cam should I get?

XE262 cam will be better in that motor In my opinion. My car has never run better with it and I have a 360
3.23 posi rear
4 speed
J-Heads
edelbrock performer RPM intake
TTI headers
Holley 650 dbl pumper carb

My car was almost undriveable with the purple 284 cam. I believe operating range is most impotartant factor in choosing, but thats just me. Good luck in your choice n Git er done!
