summit cam 1103

214-224-.442-.465 112

Comp dual energy 265DEH 12-208-4
211-221-.442-.465 110

If you ave more gear in the car you could get more agressiive on the cam
But you don't ....so..

These will both run with stock valve springs.
A new set of summit performance valve springs w retainers locks and seals is nice for max performance. low cost, drop on install.

The 416 heads are way better if ported to improve flow
1.94x 1.60 valves best.
In stock form they are just stock heads but the compression will be higher than stock but not excessive. Just right for these cams.

You will find either of these work well overall. The idle is not real agreesive.
Ok with 3.08's but 4.10's would be fun.

Good mix of power torque and mileage.

You really want to ditch that single plane intake manifold.
Big difference with the right intake manifold.
The edelbrock carb can use a bit of primary jet /rod fine tuning.
it will improve the fuel mileage. They work very well once dialed in a bit.
Use Champion RV8c or equal spark plugs @.035" gap in the 305 heads on a 350. Spark advance 34 to 36deg BTDC @ WOT.
The distributor curve may some work. They usually do.
It should run very well and make lots of power for you.
