We had a 283 / 250 in a 59 'vert, back in 71. Fell at 15.01 in O/SA
Already superceded } the aluminum Powerglide, the 62 327 smooth top FI unit, ..520 heads.
Very fast car in that year, for a couple of young guys that didn't know much.
Smoothest leaving car I ever drove, until the EFI stuff.
1972, NHRA kicked it into Super/ Stock, and ruined it. Nobody could even tell us what part was the actual manifold, and how it could be modified.
Marvin 2 Speed had an orange 57 wagon with that setup, in 72-73 . Ran pretty fair at the Winternationals. He wasn't real pleased about the situation either, as I recall.

I think it was a little stronger than the 245 combo. But , today, @ 250 hp, out of a 283, I think I'd look at more modern stuff instead.
