Holly Carb Size ?

[dbettner]

How do I tell what size and type of Holly I have ,
It is a Holly dual feed 4 Barrel but how do I tell what size and model?
A mechanic told me it was a 750 dual feed double pumper, but that sounds to big for a 350 .
The carb works perfect on my car does not run rich and has great throttle response I also get around 8 to 10 MPG. but the car is very quick and fun to drive so that does not matter.
It is a 1982 with the cross fire replaced with edelbrock intake Mallory ignition and this carb what ever size it is.
Thanks

Duane, Look on the air horn. On it should be stamped a list number. For instance, on the airhorn of my Holley is stamped 4777 which translate to a 650 CFM 4160 series double pumper. Post the number and I or someone else can cross reference it for you. And yes, double pumpers do have great throttle response. Charles

Like 72Mako said, get the part number from the driver's side of the choke horn. Then search Internet; Google is your friend. Holley information is everywhere.
