What's the scoop with the e85 carb ? Are you running e85 fuel ? Certainly the jetting would be way off if you were running a carb jetted for e85 , but were running race gas .

convertor....nothing will make a turd out of a stout combo like the wrong or damaged convertor can.

just a guess.... but what worked before is not getting it near the powerband now

Was this engine dyno tested? That would be the first thing done to eliminate what kind of power it makes.If engine is good then look at the rest of the car.

I think a big cam a tooth off would cause the valves to hit the pistons.

Back in the early 70s I broke a B + M convertor and my Cuda lost about 3 tenths, it wouldn't stall much past idle.
