AED 650 DP vs Holley 4150 650 DP

Postby Rumsawatti » Tue Oct 03, 2017 6:36 am

Hey guys, I just came across an ad for a Holley AED 650 Double pumper for a decent price. I was wondering if there was any real difference between it and what I currently have and if its worth considering. I currently have a Holley 4150 650 double pumper. Its been fully rebuilt, jetted, and tuned. The choke has been removed and the choke tower cut flat and it has been upgraded to a 4 corner idle. It runs good, no major complaints about the carb. The response I feel like could be a little better but I think that can be resolved with some more tuning. What I'm wondering is if I could expect any benefits from getting the AED. The AED looks prettier sure, but it seems like basically the same carb ultimately. Is it worth the "upgrade"? Any advice or input is appreciated. Thanks!

Really depends on your motor set up but if its running fine then no need to switch

I'm with Garry, if you switch, you might have to start tuning again, with no guarantee of improved performance. :wink: 8)

I see, Thanks for the info. I'm just wondering is there any difference between the fancy AED and the standard Holley? They both seem almost the same as far as I can tell, So why the hype about the AED?

The AED, (and other name brand Holley clones), as a rule have nicer machining and finishing, anodizing, etc. (stuff that makes em purty, :mrgreen: ), along with more, and/or easier, tuning. That aside, not much difference other than price.... :wink:
