I know a guy that bought a 67 GTX brand new. He put in a 320 degree Isky cam (the one Sox and Martin used in their '68 440 GTX) with fenderwall headers and 4.56s. He used to dump the clutch a 7200 and shift at 7200 I'm sure the car would have ETed better if he shifted it around 6000 but the point is he did that for 2 years on a stock short block. I think that's a testament to the strength of a Chrysler big block. I wouldn't recommend it though!


Now I need to pin those needles, got to feel that heat
