Which BBodies Motors Were Factory Equipped with Four-Barrel Holley?

I had a '69 coronet 500 back in the day. It was equipped with a Holley 4 barrel. I was constantly in the shop messing with that holley. A fellow mechanic had a carter in the the bottom of his tool box and he gave it to me. I didn't rebuild it, I just washed it off in the parts washer, put it on and set the idle. It ran GREAT!!!! I never messed with it again.....
 
The factory used the 4160. I don’t remember anyone putting one of those on their cars back in the late 70’s when I was watching the older guys mod their cars. The 4150, and a lot of times the dual feed, double pumper.

The vacuum secondary was probably better for most applications.

All '72 440 HP's used the same basic 4160 as the '70-71 383 HP's.

Looks the same as the one on My 70 Charger 383 HP auto AC. No electric idle solenoid though but yes on the hot idle compensator and I spy the plastic insulator on the throttle stop screw for the dist sol ground. Ahh Memories..

And this is the fix, those factory Holley’s were not very reliable for the most part.

My Holley 4160 R-4668 has been EXCEPTIONALLY reliable for the last 50+ years, in an enclosed shipping container sitting on a shelf in the garage work shop.....the OEM 1971 Dodge 500 WP23N1A****** from which the carb originated is, unfortunately, no longer with us......

The biggest repeat repair is the power valve over fueling caused by a vacuum leak
or back fire both correctable
Holley has a kit for back fire protection and straightening metering block corrects vacuum leak
 
my brothers new 69 roadrunner with factory A/C had a holley. they were actually quite troublesome, as he had to readjust it every time the temps changed. My 69 383 cuda has a holley, as does a 72 340 I removed from a 72 Roadrunner.

I have never seen a 340 with a factory installed Holley.
 
Should have been the first year with a Thermoquad, I think.
First year with Thermoquad is 71 Last year with Thermoquad was 73.

Again: I have raced these 340's continuously last 50 plus years since
new and I have NEVER seen a factory Holley AND NHRA does not recognize
it has ever been produced as such in their documentation of what is legal!

The factory service manual for the year tells the carb type and numbers and the engine sizes.

1970 book in second photo

Spend a little time looking in the factory service manual, a lot of info in there can help you learn about your car.

A lot of mis-information posted in some replies in this thread.

Yeah a 68 NewYorker 440 had a Holley. I think 70-71 the B bodies and E bodies with 383's got them.

Every 1970 B and E body with a 383 4 bbl had a Holley. No matter what the combo was. A/C, auto 4 speed, air grabber or not, and N95 emissions cars.
My 70 383 4 bbl Challenger came with an AVS.....

hey there John,
thanks to you I double checked the engine, and it actually has the 6711 factory spread bore replacement for the Thermoquad Installed. so I stand corrected!
I admit I am way more familiar with pre 70 Mopars, after 1970 I was gone and was too busy with Uncle Sam to pay attention to cars!
 
My 70 383 4 bbl Challenger came with an AVS.....
^^^^ I agree with all of you.I always said never say never when it comes to what Ma Mopar did.
Sometimes I think it was what the line worker installed from the parts bin.
Carter bin empty ? Grab a Holley.

And I'm pretty sure mine came with the AVS new as I bought the car from the original owner. The car was really nice for being a 10 year old big block car with just the interior showing some signs of wear. He changed the original wheels and hub caps out for slotted mags and went with an Accel dual point and Accel wires and that was it....so he says. And iirc, the Holley carb base is different from the AVS carbs etc?
 
This same debate comes up every now and again on these forums. The 335HP ’70-71 383HP left the factory with a Holley on it for B & E bodies, it’s well documented. There is a 330 HP 383 4bbl listed for ’70 C-body applications that spec an AVS.

Yes, the OE 4160 Hollies were quite troublesome very early on, high under hood temps lead to warpage and cork gasket shrinkage, leaking fuel bowl plugs just to name a few common problems seen at the dealers back then. When fresh the Holley’s ran well, especially the big secondary bore versions. There was factory produced AVS retrofit kits available for warranty and over the counter sales, containing all hardware necessary for a factory appearing AVS replacement for the Holley’s, choke springs, pre-bent fuel lines. The AVS in these kits had their own numbers. Installed a number of them myself. Some owners likely may not have been aware of what carb it came with originally. Never saw anything but Holley’s on ’70-71 B&E body 383HPs rolling off the trucks at the dealer.

Those claiming a factory installed AVS on a ’70 383HP B or E-body, any back-up docs to support that other than the original owner saying so? Build sheets? Dealer service records? Nothing so far has surfaced that I’ve seen.
 
It came that way when it was 10 years old means nothing. the guy changed the distributor and other stuff. Those carbs were problematic and the carter AVS was and still is the easy fix.

The build sheet will tell the story as to what it “came with” from the factory. As does the factory parts book and service manual.

The Holley and AVS base bolt to the same intake with the same carb gasket. Just need to swap the choke thermostat and fuel line.

I worked at Ford dealerships in the late 80’s. The pickups with 351 and 460’s came with Holley carbs in the early 80’s. The 4 tune up guys that worked there were rebuilding one of those Holley carbs just about daily.
