Edelbrock 650 -vs- Holley 650??

I built a mild 385 stroker motor. I want the best compromise between drivability, tunability, economy and performance I can get out of a carburetor. I'm building a daily driver that will be driven a lot. It's not going to be a garage queen.

I'm using Summit Vortec heads, Edelbrock Vortec non-Air Gap RPM intake, my compression ratio's are SCR 9.1 and DCR 7.93, I'm using a Lunati Voodoo 262/268 Hydraulic Flat Tappet Cam, 219/227 dur. @.050", .468/.489 lift, 112LSA 1400-5800 RPM range in a 350 PT# 60102, 1 5/8" full length headers and a 2 1/2" Flowmaster dual exhaust system. Going to use a 2000 RPM converter and 3.42 gears.

Which of these two 650 CFM carburetors do you think will work the best, THIS ONE or THIS ONE. I have a nice drop base air cleaner and a few other accessories for Holley carburetors.

'78 Camaro, mild Vortec head 385 stroker motor, TH350 w/ Coan 11" 2600 stall, 8.5" 10 bolt w/3.42 posi, 1 5/8" full length Hedmen Headers, 2 1/2" full length Flowmaster dual exhaust system. Going to be a daily driver/mild street performance car!

You'll receive a ton of opinions on carburators, of the two I would use the Holley, seems like more people are getting better results from them.

If it were me, I'd run a Q-jet. With your combo I think it would outperform the other two for what you want to do with the car.

Holley Street Avenger gets my vote.

Q-Jet is out of the question. I have a square bore intake and I'm not going to use an adapter, and I know nothing about them. I've used both Edelbrocks and Holley's in the past. I have the most experience with Holley's.

The 3310 is my favorite carburetor. I just don't think I need a 750 on this motor. Although I've read that 383's do like a little bigger carb then most SBC.

Performance build, okay mileage (yeah... right), and excellent tune ability HOLLEY hands down.
I have no idea how many times I've said this, but there has to be a reason holley based carbs are used on EVERY dragster and race motor (some do run q-jets but i've never seen one).
I'd say Q-jet next in line, good mileage, but I'm not sure about tune ability.

The only Mustang I'd ever own is a Fender.

I tried the edelbrock when I first built my motor 6 years ago. It lasted until I could afford a holley then hit the trash can. It wasn't worth trying to sell to someone else and I wouldnt do that to a mustang owner. Holley has been on ever since and the motor has loved it.
