But hey, that's what a lotta cars ran back in the '60's & '70's. So, you pull Jack Mullin's engine out of his wagon & put it in a GT car, it should run the index or better, I figure.

Looked up a few '63 389's, with AFB. 1 has a 250hp factor. Would be interestig to know just which 389 he's claiming.

I don't think his original car was a 'bird but could be wrong.

The big question is how did he get away with the Mullins motor? It's stick shift only.

Just sayin that some guys got quite a bit of power out of 389 engines. So, there's no reason why somebody couldn't squeeze a little more out of one, nowadays.

I'm not familiar with all the 389 combos. Have no idea which engines came with which trans. But, assume that out of all the years a 389 DID come with an auto, maybe you could find one that would make a decent GT engine.

The only 389 cars I know of that have been running lately are Norman Warling's '62 Cat Stocker & Bob Michael's '62 GP Stocker. I think they both run Tri-Power.

62 tripower 389 318hp was defactored to 275hp. As for ss to gt nothing has to change but the gt cars at same hp to weight index is .05 faster most guys do it to avoid heads up runs

Thanks for that. So, that means that any SS car can just say they wanna run GT, instead of regular SS, and that's all there is to it ?
