Is exhaust restricted, heat riser stuck, etc?
Is cam installed correctly per cam card?
Are valvesprings too weak?

WOT is function properly. No cobbled linkage. Installed just like it should be. I swapped the carb with another earlier today.
Tried two different coils.
New plugs. Replaced fairly clean old plugs.
Exhaust is clear.
Haven't looked at the cam.
Valvesprings; These are preassembled Edelbrock Heads with low use. If the springs are weak they were defective. I hear that's a long shot.
