Edelbrock 650 vs holley 650

[synthartist69]

Hey guys,

From the information I have gathered it is looking like I need to go with a 650 on my set up. I like the Edelbrock Thunder 1806. But I am reading that people have had trouble with throttle response and overall power. I would like to know more about it and if a Holley 650 would be better for me. Two things I don't like about the Holley is that it is a spread bore and my performer rpm intake is a square bore so now I would need an adapter. Also, the Holley requires a dual line inlet and the edelbrock does not. I would love to hear your comments on these carbs...Again here is the set up..


This will be a street/highway racer....no dragstrip. Here is the set up...

1965 mustang GT350 tribute

Hipo manifolds...for now (headers later)
Pro Comp castings

3.55 rear end
T5Z 5 speed (,63 5th gear)

Are you positive the Holley is a spread bore?
Speaking from personal experience. If I want Performance and I dont mind fiddling a lot with the carb to dial it in just right, and every 6 months or so fixing little issues that seem to appear, I recommend a Holley. If I want to bolt it on and go, I recomend the Edelbrock. The Edelbrock is also easy to tune without removing it and draining the float bowls to change Jets or Metering rods. It just seems like I get more power from a Holley of the same CFM. My fave is the 670 Street dominator.
