KrazyRay · 01-05-2012, 02:35 PM

This carb was working great on my gmc 6500 garbage truck with a tall deck 454 when I pulled the engine out a few months ago. $100 shipped.
Thanks,
Ray

Hey Ray. Not trying to be a dick, but that is a vaccum secondary carb. Double pumpers are mechanical secondaries with an accelerator pump on the rear bowl as well. Just trying to help. thanks, Fred

Ray, what numbers are on the front of the choke horn? I might be interested in it. Thanks Ryan.

Thanks for the education...I thought they were the dual float bowls.

Ok, thanks. This carb is a "Dual Feed" that's why it has the line going to the rear bowl from the front bowl. If it was a double pumper, it would have another accelerator pump on the RH bottom corner of the rear fuel bowl.

The only thing I can find is the words Holley and LEAH.
I hope this helps.

Hey Ray. On the airhorn, there should be some numbers, probably something like R3310-3. That would be the list number. Hope this helps.
