Hi everyone!

Im looking into buying a carburetor for my sbc. I was looking at a holley 3310 and a 750 speed demon.

Well the holley is a bit big and costs a lot of money even if you just buy a rebuildable core.

The speed demon is mildly cheaper, has annular boosters for better fuel control of the 750cfm on a small block and has alot of other cool little features. BUT! Alot of the problems that have been surfacing with demon carbs lately have kinda scared me off.

SO I have a chance to buy a 625 cfm Carter AFB Carb. That was just rebuilt and has a guruntee that it will work or it will be fixed for free. So what do you guys think about Carter carbs? Ive never even seen one up close. Do they work nice? Good performance? Also my quadrajet I have right now is the wrong bolt pattern {spreadbore} would the carter be the right pattern? {which would be squarebore,Correct?}.

Any other tips would be greatly appreciated, Id be getting a good deal on the carter. Here are my engine specs.
