Hello,

I'm getting rid of my holley double pump and looking to go a different route? Any recommendations for my set up? I cruise around town and like to haul ass from time to time but not racing. Street avenger? Demon? EFI kit? Thanks!

What’s wrong with the Holley? What size is it?

What’s wrong with the Holley? What size is it?

Double pump for an AOD not ideal.

Something rated around 600 cfm with vacuum secondaries. Holley, Summit and Edelbrock all have their fans.

I’d get a Summit carb 600 Vacuum Secondary. EFI a whole different game. I’m all for it but it’s not cheap

Nothing, just never really liked it. 4 barrel holley 8050B double pump

I know now I got suckered when I bought the carb.

 

[Abejauregui]

How much should I spend on a new carb, or should I really look at the efi kit from Holley.. more $$$ obviously. weighing pros vs cons

 

[fordguy]

if you like the holley, i'd get a street avenger 570

Keep the carb and change to 3.73 or 4.11 gears and a 4 speed.. or keep the automatic and go EFI with a little turbo

All the 8050B's that I have seen are vacuum secondary. Does it look like this:

the double pump holley. I bought new years ago at a speed shop. Now I want to see what other directions I can go based on opinions.

Summit M2008VS500 for a 289-302 with stock heads. M2008VS600 for aluminum heads or modified stockers.

Which 4 bbl carb is like asking which 4 door car to buy. LOTS of options, many based on preference.

I think the vast majority of people would agree to get something that does not exceed 600 cfm and has vacuum secondaries for a street automatic.

This goes through the differences in carb brands:

Abe, the carb you want is a Holley 4010 or the Summit version thereof or a 1.12 Autolite 4100. All of these are 'shoebox' carbs, well designed and generally trouble free. LSG

Not a damn one of them! I'll soon be 67 and that's not old enough to drive a 4 door car. Long live the 2 door Mustang!

+1 to the Summit M2008VS500 , runs great right out of the box

I put a 500 cfm Edelbrock on my wife's 302 some 15 years ago when she was driving it everyday. Still on there, I still like it and wouldn't change it.
I was never big on using a double pumper with a streetable automatic. I think they work better with a manual transmission or a "race built" sort of automatic. It's probably easiest switching to another Holley so you don't have to change your whole setup.
With either, AOD operation is enhanced with a "TC corrector" that fits on the linkage. You have to pick a Holley or Edelbrock though. Or be goofy like me and just by a corrector for each.
If the field's wide open, a rack of Webers is pretty darn cool. Not sure how you'd hook an AOD's TV linkage to that. Where there's a will there's a way though.

Thanks. I haven’t been a fan of this double pump. It’s hard to tune and get it just right with the 302

Autolight 4100 enough said changed my car
