I,m slowly but surely putting the GTX back together and have got some great help on here.I,m getting ahead of myself,but since I,m waiting for parts to finish putting the top end back together on the 440 I have question about the carb. I have the original Carter AVS,in fact I think it was on there when I took the car off the road 10 yrs ago.I also have a Holley 750 performance series carb that I bought years ago with the intent of putting on the car.Since the 440 is staying stock other than the six pack spec cam,which carb would work best? I,m wondering if the 750 would be too much for the stock 440.And if I,m keeping the AVS,are rebuild kits still available? shruggy

If you desire correct than AVS but it will never perform like that Holley.

As a 53 year old motorhead since 14 years oil I believe that if you want to just drive the car and aren't worried about every tenth of et's the AVS is an awesome choice.

Carter is good carb. If you arw building a warmed over or high peeformance street motor, they work great, and they are very easy to work on. I've done a bunch of them and the first one I did I had zero experience with carbs. Even if I knew how to work on holley carbs, I'd still use a carter or edelbrock on warmed over or stock engine just cause they are so cheap, simple and work so well

And yes there are rebuild kits.

the avs will perform as well as any 750-800 holley. the issue is the emissions built into the carb. there are idle mixture screws under some lead plugs at the base of the carb that will need to be uncovered for mixture adjustments. the idle jet is probably too small and can be easily enlarged. you can end up with a trouble free carb that will perform as well as any comparable holley.

I agree, nothing wrong with the stock AVS at all. What year is your car?

They say there are no such thing as a stupid question.
They say there is always the exception that proves the rule.
Don't be the exception.

All (OE '68-'71) AVS's are lean from Ma trying to meet the discombobulated Federal emission standards of the day (Furd/Chebby too). convert it to use Eddy Performer 2 step metering rods/jets. Fill the domed metering rod caps with JBweld then cover it with scotch tape then turn it over & let it set for 2 days so the mud will settle & harden out level then pull the scotch tape. Start with a rod/jet combo several tho larger (richer) than (AVS) stock on the power/cruise steps & go from there. Purchase a strip kit with rods/jets close to the dia's your AVS has

The avs will be fine. The holley will be fine. Which do you feel most comfortable working on? Sounds like the car is mostly stockish so the avs woukd look more "correct" and you likely have the oem fuel line already.


I want my fair share

What is the primary throttle blade bore size of the AVS?
1-11/16 = 750 cfm. so if same CFM, which one is in better condition?
I'd check the throttle shafts for wear, it could make the decision easier if one is really sloppy. If same CFM and condition, it would come down to preference.

If you are not set on 100% stock and have a little $ to spend why not try the Street Demon carb? Youd have a brand new carb and its intended target is high perf street driven vehicles.


Keep old mopars alive.

look at the front of the carb and see if the numbers 4640s are stamped on it. i have a '69 r/t 440 auto with it's original 4618s avs. what i've done is change out the leather accelerator pump plunger for newer viton edelbrock. i use the stock .101 tall primary jets with a 16-575 metering rod (.065/.060/.052 three step. these are no longer available but an edelbrock .065/.052 will work). stock .095 jets in the back will work with a stock engine. i've unplugged the mixture screws at the base of the carb and they're backed out 3 1/2 turns. the only "tricky" part is the idle jet. it's the small brass tube that hangs out the bottom of the primary cluster. these are .031" from the factory, too small. i've tried several sizes from .031" to .040". i've settled on .033" which is a tad lean (manual transmission carbs used .035" which is about right). i use a .028" afb squirter i modified to fit the avs (simple to do) and have the pump shot rod in the top hole. this carb starts, drives and performs quit well with the near stock engine (summit 6401 cam; idles smooth, very good low end). keeping the avs lets retain all the stock linkage and choke assembly and you give absolutely nothing up in performance to a comparable holley.

it is a 4640s. I still have the metal tag that mounts on the base of the carb with 4640s stamped on it. The car ran decent when it had the Carter on it way back when,just didnt have a lot of guts for a Big block.I did narrow things down to the upper end of the motor and had the heads rebuilt and installed the Comp cam,so I dont thing the Carter was a problem.While it was apart,thats when I bought the Holley,just never used it.

A 750 AVS was a stock carb on performance 440's. Keep it, cheap, reliable, makes good power, easy to tune. While there not as tunes me as a Holley due to the multiple tuning points a Holley "can" have, the Carter will work very well.

Many say Holley but fail to mention which one of the many or which manufacturer or modifier of Holley to go with. Since there hundreds to pick from and then modify yet again, it should prove to be an outstanding carb. But it doesn't.

The abilty to tune a carb is key. No matter what carb you have on top.

Chuck, I'd say rebuild the AVS and start there. If you don't like it, try the Carter.

I switched my 1967 2bbl 383 Satellite over to an AVS 8 years ago, never regretted it for a moment. I'm not a performance guru, but like to have some power. Easy to rebuild, easy to drive, no fuss no muss.

You've got the tag, so for a kit just call Larry Isgro Carburetors, he is on Long Island unless he retired, but I've been getting my rebuild kits from him since 2001. http://www.yelp.com/biz/larry-isgro-carburetors-wantagh

LOL

The Holley 4150 is an engine fire waiting to happen

If you have the Carter 4640S use it
