What size is this holley?

[BigTruckDrivah]

The only number I could find on it was 3310-3. I looked it up but couldnt find this number exactly. I could only find a 3310, but that was listed as a non double pumper 750 cfm. Anyone got any ideas?

Well it's not a double pumper....

[em98ss]

looks like a double pumper to me, you have a dual fuel feedline to the front and back bowl. A single pumper, just has one fuel inlet, and a small tube going back to the back bowl don't they?
Does it have two excel. pumps on it?

it's a strong possibility it's either a 750 or 780

Doea have 2 fuel bowls. Does not have 2 pumps. Does not have dual metering blocks.

LIST # is the best number to have to find the replacement parts.

I got a Ho;;ey catalog somewhere dammit!

The only number I could find was 3310-3. I'm not big fan of holley, infact if someone had an edelbrock 4 barrel Id swap for it. Maybe even toss some cash in.

I have a Hoey book...lol

[BigTruckDrivah]

Cool, thanks guys. If I wanted a edelbrock, would I look for the same cfm rating or are they rated different?

That is one of Holley's "standard' street carbs... you can get them pretty cheap.

As fas as the carb size goes, are you sure the Holley 750 was the right size for this application? Too big of a carb equals lower horse power/torque output, poor drivability and stumble. If the carb is too small it creates a restriction in the intake.

I havnt drove it due to the trans, but it runs like top with it. No stumble, hesitation. It has great response too. And it sat for almost two years. I may give it try, it needs freshened up, it's leaking from the throttle linkage.
