First Time User Here But plenty of experience with Chevy, GMC...
found a inexpensive Holley 650 Duel line, part number on carb [List 4777 0805]...What does this fit? I have a 1986 GMC 3500 (1 Ton) with a 350 (small block) needs a carb. Can I use an adapter to fit a 4777 to the manifold?

Welcome! You won't get many questions like that answered in the introduction forum, post the question in the engines forum and you will get what you need I am sure.

Not installed on any stock production vehicle. Aftermkt. double pump carb. For off road use.

Will turn your basic stock, heavy truck, into a gas guzzling, plug fouling, loaded up pain in the rear to drive.

650 double pumper is a great carb.It doesnt hesitate and it flows enough for 400 hp.I used the 4777 on my 283 back when I was a teen.
