426 stroker dropped in scamp
I’m a firm believer in “never say never”....... up to a point.
600hp 273-2 on 87 octane?
I’ll call BS on that.
The obscure race stuff?
Eh..... who knows.
Go to the track, make some runs, go across the scales...... put a go-pro in the car, etc.
I don’t see anything that would prohibit the OP’s motor from turning 8k.
The question is.......Is it making power up there?
