For sale... Holley 750cfm  (3310) Vacuum secondary carb.

This is George's old carb off his 68 Vette. Still had gas in it when i got it. 

Eric made me an offer i can't refuse on the 850dp proform I borrowed, So need to sell off some extra stuff to raise $$ to pay for it.

 

$100 for TCNW

You may want to keep the 3310. I have one that I tuned for my 454 and it is really nice for a street car. Also it made 4 more HP than my DP on the same chassis dyno and had nice manors on the street with great throttle response. Its only down fall was the sloppy front throttle shaft. I may even take it to the track and see the best times I can get out of it.
Don't throw it out just because its an old VS.

Not throwing it out by any means... I just want the other one. However- if i can't get a few items sold in short order I'll wind up having to keep and run it- don't have the $$ to throw down when i still have other things on the car that need to be purchased first.

May as well take the bowls off the 3310 and check the jets and the PV may be bad, they don't last long with our shitty gas. I run 74/84 with a 4.5 PV, you could run a 6.5 for your mild cam.
I think it would be a good street carb. I had one on my 396 4 speed years ago, worked nice.

Just my 2 cent's.
There is nothing wrong with a V/S carb.

If you are staying below 6000 rpm with a 454.
The 3310 will out perform the 850dp everywhere except the track, and not by much if it even does at all.

 No secondary metering block. 

Looks like this except the choke blade & mechanism has been removed.

The ones without a metering block run way rich and kill HP at WOT.

Nah.. Nah.. its a killer carb! I'm a fool for selling it! perfect for a budget biscane! $80 for you! You buy now! 

 

Seriously I'm positive its a great carb. It came right off geoges vette, still had gas in the bowl & acc pump when i got it.
