I was thinking of getting the 770 for my 383, i was wondering if anyone has used these carbs, and if they are any good??

 

I have never really cared for Holley that much. Mine has always needed to be tuned a lot. I don't mind it when they come from teh factory on a car/truck and are in great working order though.

If you have had them before and know how to get them to work, then I say go for it. Otherwise I'd go with an Edlebrock AVS where the secondaries are adjustable with a screw.

 

i heard that they are great for power
