I have a 4bbl Carter on my 67' 302 rebuilt motor w/ Eldebrock performance289 intake.I would like to replace w/Holley,possibly 600cfm 4bbl or comparable.I'm looking for performance,reliability, and of course good mileage.(can you mix those three???)What is the best swap and where can I find it without breaking the bank.I've found several suppliers through ebay ,but there are so many choices I figured I'd get some feedback on personal experiences.

 

The Holley Street Avenger seems to fill your order. I seem to get great gas mileage(in between fill-ups becasue my sending unit is still broken) and outstanding performance. The throttle response is outstanding as well.

 

Thanks Mike,I'm looking at one right now,its a570CFM for about $300,offered by smmenterprises,out of Chesterton,Ind.They've got good feedback,so it looks like a safe bet.Sure looks worth consideration.
