OK here's the deal.
74 still is breaking up on both sides under load.
Starts and runs fine until I give it 3/4 pedal or more.
New plugs and wires
New HEI distributor/set timing
New fuel filter and new gas
Carb is HP 700CFM DP
Turned mixture screws in and engine died, means power valves ok
I give up Any ideas welcome
