Stock stroke 340 with a 4 speed and 3.73’s?

Let’s hear the rest the of the cam specs........ but off the top of my head I’d say it’s way too big.

That trans/gear combo with closed exhaust isn’t going to need/want much cam at all.

Warm up the motor, do a compression test on a couple cylinders.

5 “pumps”, and then however many it takes to max out the gauge.

LOL...that's what I said. But since I'm old school there is no such thing as a cam that's too big...you just don't have enough gear.

I agree...if the OP isn't willing to stick some gear to it he is way off on cam, and my guess is he did the dot to dot and the cam is retarded to boot.
