Edelbrock vs. Holley
OK...I'll declare my ignorance right now....That's why I'm asking all of you.
I am in the process of rebuilding my 460 to go in my '76 F250. The old Holley on the motor is very well shot.
I will be purchasing a different carb and I would like an HONEST opinion of what to go with. The engine will retain the stock 4 bbl intake.
I know that holley carbs always had a problem with blowing out power valves.
I have been hearing good things about the Edelbrocks so I wanted to know the opinions of others.
So, Holley or Edelbrock and what cfm?
Thanks!

It all depends on your personal opinion. I prefer Edelbrock. I've had bad luck with Holleys in the past, but my Edelbrock has been running great with no trouble for over 5 years now. The Holleys generally take more gas and require frequent tuning and maintenance. Where as the Edelbrock doesn't need the constant attention, and seems to runs smoother and is more dependable for a year round daily driver. The new Holley truck avenger carb is good, with protection for the power valves, but I'd still get a Edelbrock. I'm running a 600 cfm with electric choke on my '73 2wd stock 390 and it runs great.

For CFM check this out:

Edelbrock is way ahead in my book. Much easier to jet. It seems to me that most carbs come jetted too fat out of the box and can stand to be leaned out. The AFB is really easy to tune and you should order the jet/rod/spring kit with it, I think it is about 50 or 60 bucks for the one with everything you would ever need to tune an AFB.

A 670 Street Avenger Holley if you are really concerned about mpg and your motor is bone stock, otherwise a 770 SA Holley, especially if you have free flowing exhaust. That would be my preference. I've used them all, but I'm not a fan of eboks, although I agree that they are easier to tune for the novice. Honestly, unless you are building your motor for power, either brand would be fine.
edit: Holleys have had "power valve blowout protection" for some time now.

holley is the best. edelbrocks work well but they give your engine about 85% of what it should have. a 460 NEEDS a 750 holley, vac secondaries. the power valves wont blow out anymore, in the early 90s holley installed a check valve to protect it so on a newer carb youll be safe. PLEASE GET THE HOLLEY, edelbrocks are non-tunable ive had both...........if you do some basic research and learn how the holleys are tuned and adjusted you will have a tire blistering big block.

I have a 600 holley 4 barrel on my dune buggey and it has back fired many times toying with the timeing and such, never blown a power valve.
Also, the chibbie I am driving has a edelcrap on it and I have too retune every time the weather changes, witch means every day here in south texas.
