I have 2 carbs I am wanting to sell, both are in good working order with recent rebuilds, like within the ast month. They are both vacuum secondary and the 650 is a single line and the 780 is a dual line . The 650 is standard but the 780 has a secondary metering block with a secondary power valve but no 4 corner idle system. list number is 3310. I ran the 780 holley on my corvette for about a year or so and I never had a single problem with it, actually I love that carb but I switched to a demon carb which I dont like as much lol. I will take 175.00 for the 650 and I will take 250 for the 780.

I forgot, I would mainly be lookin to trade for an 85 lx front bumper and a hood, but will consider others. also here is a pic of the 780 and the 650. I dont have any super good pics of either but you get the idea.

The 3310 should be a 750 vacuum secondary .
