318 Torque cam
I would go with a comp XE cam.The technology on these cams compared to the old Mopar purple shaft is like night and day.
The XE268 might be a little much,maybe go for the XE256 or XE262.
The best thing to do is call Comp Cam tech line and tell them your set-up,and let them pick the correct cam.
For intake,the Edelbrock performer would be hard to beat.
Carb,Edelbrock 650 vacuum sec would work very nice.
This combo will give you a very fun,streetable car !!!
Here is a pic of a 318 I had.
Stock 1970 block/cam
Edelbrock performer
Edelbrock 650
340 manifolds
2.50" Dual exhaust H-pipe
Mopar performance ignition
This set-up would roast the tires.
Could only imagine your 302 heads and a Comp XE cam.:tonqe:
