On my last 2 Edlebrocks, I just used a generic 4 hole 1 inch plastic spacer that I picked up at a swap meet. It really doesn't matter much what you use, as long as it insulates the carburetor from the manifold heat. You could probably make one out of a piece of wood and it would work just fine.

IBZ, pics of the 4 hole style phenolic spacer I use. Will require longer carb studs but they can be had at most decent parts houses, even O'reilly, Auto Zone etc. I DO NOT use the full open QJ style figuring without the 4 smaller seperate venturi openings that match the Carter/lEdelbrock base plate, the full open style would cause a turbulence to the air downflow. ??? Not sure bout that but seems reasonable to me. The spacer is 1'' thick, could use 1/2'' also, the smooth flat portion is the top which goes against the carb baseplate, the more open portion goes to the intake / gasket area. Not familiar with the HVH logo, picked this up at a swap meet for $5 just to have a spare. Hope this helps and good luck with your carb issues.

Got curious and Googled: " HVH Phenolic carb spacer " Came up at being High Velocity Heads, an aftermarket speed/race product company. Spacer sells thru Jegs for $89.00 plus ship so guess the $5 was well spent.

'68OrangeSunshine, thanks for the info on the #9625A carb. I was told it was an Edelbrock when I bought it at a swap meet years ago, $15-20 don't recall for sure. Used an Edelbrock kit for the rebuild and works great, truck is quite healthy when I push the romp on it pedal. Never checked the carb # thru Google, Google is your friend as they say. I use it a lot.

Im also running a 5psi regulator before the carb. I also had alot of problems with jetting. Doing research the 1406 is jetted leaner than the 1405 manual choke model. I rejetted the 1406 to the 1405 specs. Truck runs very well now, it has a stock mr gasket crate 350.

Tomato, tomahto. Basicially the same carb with 2 different retail vendors at one time. Now only one.
Like GMC/ Chevy... Rolls Royce/ Bentley. The badging affects the price tag, not the internal quality.
Good score.
Just remember when you call Edelbrock's tech line, don't let on that you have a Carter AFB, they'll dummy up.
Some matches:
Edl-1405 = AFB 9625A
Edl-1400 = AFB 9635 [w/EGR]

Also is the stock spacer with the tube angled on it needed if it's not hooked up to anything, I also attached pictures of my engine which as you can see doesn't have the phenolic spacer which I will put on when I get one.

After looking at the pic I would say that is not an original air breather spacer for the 67-72 trucks. Does not seem tall enough and the tube comes off at a straight level, not angled back and down like would be on an original. would originally be rotated back further towards the distributor. I see you are using a push-in style breather on the passenger side valve cover. That valve cover hole would normally be used to connect to the air breather spacer thru a rubber hose with an end fitting similar to a PCV valve which has a screened flame arrester pushed into the valve cover hole with a rubber grommet. The purpose of that hose is to draw off crankcase pressure and fumes up from the valve cover into the breather and on into the carb to be burned and exit thru the engine exhaust. As you have it now, the spacer being plugged off and using the push in breather cap is fine. Hope all that makes sense, maybe another member can chime in with a better explanation.

I know this is an old thread. I have just installed a Eldelbrock carb. Question is I have the throttle cable that goes into a bracket with the rubber grommet. I installed the ball on the carb for the linkage but if I use my original bracket the throttle cable is to long. Any help. Only reason for switching carbs is that the divorced choke spring is broke.
