8 or 8.5:1 ? Good set of heads, at least i would replace those stockers. What is the casting number on them?

Pull all the plugs, disconnect the coil, wire the throttle blades open and do a compression test on all cylinders. SURPRISE!!!

The site I used said they were 76cc chambers off a 350 or 400 they were used on both engines I guess. Didnt find anything on the flow numbers. Let me know if you can find it or know off the top of your head. Any hp guesses. Maybe with a set of heads? What about a set of camel hump or vortech heads off a newer block.

What about a set of full home ported #416 305 heads with 1.94 intake valves to get the cr way up and the airflow up. Install with a felpro #1094 gasket.
Move the 292H cam to a 102-103 intake C/L.
Lock out the distributor mechanical advance (34-36deg locked timing)
You'll have a whole different opinion of this motor.
get a 3500 stall converter and some rear gear.

As you have it configured now (no cr and no head flow) you'll find its pretty weak.
