Holley Carb to Stock Intake Manifold Suggestions.

[TimS]

Do any of the square bore Holleys bolt up to a stock cast iron intake without having to use a spacer. I want to go to a Holley on my 69 Roadrunner with original intake manifold?

I tried a 4160 with electric choke but had interference issues with the throttle and choke linkages.

I've run a Holley 750 vacuum secondary 3310 on a stock manifold with no spacers at all. I had to clearance the side of the intake about 1/8", right on the passenger side where the carb bolts up + also clearance about 1/4" off the bottom of the carburetor return stop (?)….I'd have to look at the carb. No problems at all & I drove the car with this 4 bbl. & stock intake for many years.

Did your 3310 have an electric choke on it or was it manual?

Manual choke. I still have the carburetor & intake. It's only a minor modification.
