Re: 1968 Motion drag car on the street
I put one of those gear drive units on my 780 Holley back then. The primaries and secondaries were geared one to one and the accelerator pump squirter extended through two holes you had to drill to feed the secondary side. Didn't do anything for performance but the gas mileage was about half of normal which wasn't great to begin with. I think that a lot of people tried this same thing because I have had to look some to find an original carb that hadn't been drilled. Live and learn.
