'57 Chevy Rochester Fuel Injection
 

I debated whether to post this here or in the Nostalgia thread, figured there is more exposure here.
I just read a story about the Black Widow Stock car and it sparked my interest.

Who if anyone, runs this combination in Stock, Super Stock or Nostalgia classes or has experience, knowledge or stories to tell us about it

I forget about that infamous car.

Re: '57 Chevy Rochester Fuel Injection
 

We had a few running around here in ‘57. Local guy, Jerry Weiderman won “The Nationals” (way before Indy) in either ‘57 or ‘58 with one. Drove it on the street as well.
Three speed, still on the column back then.

The car is now enjoying life in a Tennessee rest home after surviving an accident in Bowling Green, Ky.......

If you ever go to the Petersen Museum in Los Angeles, it is well worth paying a few extra bucks to take a tour of the vault. They have an original 57 Chevy “Black Widow” drag car that was in the vault when we went through a couple of years ago. The Black Widows were built by SEDCO with “back-door” funding from Chevrolet and this particular car was diverted from NASCAR to drag racing where it ran in G/Stock.

Just read the info on the Black Widow '57 Chev.Wrong info on the engine Specs! Solid Lifter F.I. engine was rated 283 H.P.-not 250! 250H.P. engine had hydraulic lifters.

Way back when, I lived in Temple City, Calif, and it was a quiet working stiff community but also there were a lot of car people around. We used to see an older gentleman driving a red 57 Bel Air sports sedan, that was the 4 door pillar less hardtop. This one was red, white top, and original right down to the hubcaps. The real draw was that both front fenders had large crossed flag emblems and the rare as could be Fuel Injection badges. It had the Powerglide trans in it, so it would have been the 283/250 horse motor. When discussing that car at work one day, a sales manager told us that several were built for salesmen's demonstrator cars. They were fairly decked out with options for back then and had lots of extra trim options.Seemed like over the years, a lot of car guys that I knew had seen that car running around, nobody had any luck trying to buy it. Hope somebody eventually got it and gave it a good home.

OMG, too cool.

Re: '57 Chevy Rochester Fuel Injection
 

I think Bill Parmenter tried the fuel injection in his 57 super stock years ago without much success. I believe the only difference from 250 hp to 283 hp is camshaft. His nephew Mike is on here sometimes he might know how it ran. My experience is back in the 60"s trying to get one to run properly and i remember high vacuum was needed to make one run decent. With our weird camshafts that would be a challenge.

look up Gerry Stinner from the Truppi/kilng days he should know a bunch, Ralph did a few back in the day.

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?

283/250HP = flat top piston = 9.5 to 1 +/- = .398/.298 lift hydraulic lifter

283/283HP = .122 dome = 10.5 to 1 +/- = .394/.400 lift solid lifter

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
 

Bill did try fuel injection quite some time ago. Thinking mid to late 90’s. It was very consistent, he won a super Chevy show race at Portland with it but was not able to run the index. Dual quads were faster by a bit and carried less horse power. To be fair they were on a tunnel ram with porting and the fuel injection was an untouched original manifold. He might have used the later 327 injectors, memory fails here. Maybe a sheet metal manifold would help? Specific questions might jar the memory so ask if you have any!

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.
