Disappointed with my engine

Okay Mr Rusty RR what was your input?
Was it you that said Mopar heads were the pick of the bunch way back when ? Ha ha ha what a joke. Have you ever looked at a Ford Cleveland from 1971 - 86. I don't think you guys had 302 C in the US did you? Maybe you should have said that they have a higher exhaust port than a Chev which would have made them the pick of a bad bunch It was inferred by myself in my origional post the heads were the issue.
The other thing you suggested was overall car set up. I'm 64 mate and first went down a racetrack in a FED more than 40 years ago. I can promise you this, there is Zero, did you get that, Zero, similarity between a door car set-up and a 1400 lbs slingshot. None.
I welcome your and anybody else's input but keep it real.
I'm very familiar with Cleveland heads, since I have a complete 70 M code 351 in my spare bedroom. And yes, I've seen a couple of 302C engines. NOT Boss 302. 302C. They are different.
