Re: '57 Chevy Rochester Fuel Injection
There was somebody back in the 60s or early 70s that raced a winning Corvette that had the Rochester fuel injections with what we would call today dual throttle bodies on it.
I think he raced mostly, if not exclusively AHRA. I think he was from Texas. Does anybody remember this car? |

Re: '57 Chevy Rochester Fuel Injection
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Already superceded } the aluminum Powerglide, the 62 327 smooth top FI unit, ..520 heads.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.

Re: '57 Chevy Rochester Fuel Injection
I own a 1959 Impala Convertible Fuel Injection car. 283 290h.p. The fuel injection units need 11 inches of vaccum at idle. But you can put as much fuel to them as you need. The air meter flows between 650-700 cfm stock.... i think you could make one work fairly well, but would take some time and dedication.
