I was looking on Summit racing and I noticed they have remanufactured carbs from Quick Fuel which I heard were decent carbs in both 650cfm and 750 cfm. Does anyone have any experience with those carbs or know any info on them. I'm also thinking about a Holley Street avenger 770 cfm for my 455 build, but on Summit they list the same carb, or what appears to be same 770 cfm street avnger 3 times with 3 different prices. Any ideas on what the right one for my application would be?

Just be aware of the fuel bowls. Some have an option of being able to run your lines on either side, and the other side must be plugged. Problem is.... The plugs can rattle out and catch your car on fire. Not just a little bit.... a lot of bit.

 

Does this apply to the remanufactured quickfuel carbs or the holley street avenger or both? I'm confused as to what that means exactly.
