is it worth installing cam in stock 318?

On my stock 318 with a 904 (A low comp. '79 engine/drivetrain) & 3.21 sure griped gear set, I added;

600 AFB
Edelbrock intake (LD4B)
Hooker headers and a Jegs Dual exhaust @ 2-1/2 inchs.
Stock tire height (?) 225/70/14
Cam was a Crane 216/228-.454/.480 CL-112.
Dead stock heads

First run @ ATCO on a cold Oct./Nov. (I forget) day ran me a 15/14 @ 89. I later tuned it and gained a nice seat of the pants gain. I never took it to the strip though.

(That whiplash cam idea is a preety good one.)
