I can tell you this much: it was never, ever used in PRODUCTION on any Corvette, 1964 or otherwise.

That I don't know. Some of the early FI afficionados, especially someone like Ken Kayser, would probably know.

I remember John Eyestone having a dual meter F.I. unit. Legend has it it was a racing unit.

Matt,

Bill Thomas of Cheetah fame modified some pre 63 units with dual air horns but I have never seen a 63-65 unit done in this manner.

It would look so cool on my 65...

Here are a few pictures of modified 2 air horn Rochester units:





Tom Parsons and Jim Lockwood,s names were mentioned as being knowlegable of these types of modifications .

Re: odd 64 fuel injection set up

I have seen a couple of the top mounted horns on Bill Thomas units and one side mounted like this one. I have some pics somewhere on Cheetah and '63 Corvette (a white GS before body mods IIRC).

As others have indicated, this FI unit has been modified to accommodate dual air meters. In all probability, the original reason would have been for racing purposes. In any event, to make dual air meters operate properly also requires modifications to spill valve in the fuel meter. It's not as simple as bolting on the 2nd air meter and going for a spin.

I'm not aware of any units that left RP with dual air meters, but I'd never say it never happened.

It would have been nice if the listing had included more pictures. The asking price is pretty steep with no more information than was included.

Yes, usually the folks willing to spend BIG $$$$ are those looking for factory-original parts, not modified/experimental pieces. Of course, if this were a unit that was originally used on some famous race car, that would be a different story (assuming a potential buyer actually owned that car).

Re: odd 64 fuel injection set up

I find it strange that the unit has a choke on the front air meter.
Typically not seen on race setups, I believe.

Re: odd 64 fuel injection set up

Personally not my cup of tea although i worked on a Gulf Research unit a few times. All we did is try and figure out the linkage abortion so the unit could be on display at the NCRS national at Seven Springs in the old days.
Guys do not realize the importance of the forward balance tubes. On some of those units if the tube is not squeaky tight it affects the cars idle and performance.
Bruce, I agree with you on the choke. It has a choke housing but it doesn't have any other choke parts. No fast idle cam, no choke rod, etc. So what the choke housing is doing is questionable. Maybe it's there just to open the choke butterfly.
Meanwhile I was never interested in dual air meter units although they were offered to me over the years. Hard enough to get a stock unit running dead nuts for PV.
Grady Davis was not that successful on those Gulf Research units according to their mechanic Joe Dzorchak (sp)
He said it was basicially just an experiment and having some fun. Joe also worked for Don Yenko and was was Don's best FI guy in the old days. He's gone now.

Re: odd 64 fuel injection set up

I looked at the testing data and see that the right side was running leaner than the left. On my road race FI unit this has been a constant problem. It seems to be amplified by higher flow rates. I don't really have a good or even plausible reason why this is so but this test data seems to confirm what I see. Jerry

Re: odd 64 fuel injection set up

http://www.micro-controls.com/fiparts-63spiders.html would changing the length of the tubing on one side change that ??? looks to me that all the tubing is the same length and that must be for a reason
