<VV> Holley 500 or Not

[jwcorvair at aol.com]

To answer your last question first, yes the Rochester is a 4GC. Unfortunately, I know nothing about the 4GC or I might work on?it.

I actually would prefer to go to the original Corvair carb system. This engine, however, is not in a Corvair and I do not have any of the linkages,?studs, or gas lines?to return it to a Corvair configuration. One day I plan on reverting back to the Corvair Rochester H carbs that are built for some performance. My thinking is that if I can a reasonably priced Holley 350 (thanks for the suggestion), I can more quickly correct the car's drivability issues. I may be all wet though.

I recall reading, either on VV or the Corvair Center, that the Holley 500 was a good choice for a carb on a single manifold on a 110 engine. Has anyone had any experience with a Holley 500 on a 110? If so, how did you set up the carb. I currently have a 110 engine with a Rochester 4-barrel that I drive in town. The 4-barrel is not the smoothest set up - stumbling on leaving a stop light, tendency to stall. Maybe the 4-barrel needs more work. I'm not certain because I did not install this setup on the engine. Also, the mileage is terrible in town (actually quite good on the highway, though). Any thoughts or comments are appreciated.

If you change to a 2-barrel carb, and want to use a Holley, I would go to a 350 CFM 2-barrel, such as this one from Summit Racing.

It has the center pivot floats but is better sized to your manifold/head combination. There are adapters made to place the Holley (same pattern as the 500 CFM) in place of your Rochester. Is your Rochester a "4GC" model?

You might still consider going back to the Corvair carbs. Great on a 110 motor.
