Well, I didn't have the $100 to shell out for a Proform main body, and eBay didn't have any going any cheaper at the time, so I did some work myself. I didn't really hit the venturi's real good, b/c I don't trust myself not to accadentally change the shape. Anyway, here is a pic.

 

looks like nice work, but the cool thing about the proform is the screw in airbleeds.......

but, for nothing out of pocket, you should see some gains.

Yeah, I thought of that. But after reading the article in Car Craft I think on tuning with air bleeds. They didn't gain much in terms of drivability compared to a non-air bleed tunable Holley. But, that is one thing I do not have.

 

Can you explain what you did?? Sorry....new carb guy here.

 

Sure. It originally looked like the pic below. I took a cut off wheel and trimmed the choke horn off. Then made a series of vertical cuts next to the air cleaner stud hole. I took some plyers and broke off the little pieces very carefully. I then took a die grinder with a carbide bur, and smoothed out the rest. After that was done, I used some sanding rolls from my SA Porting kit, and did the rest. To finish it up, I used the cross buffs in the kit to smooth it out real nice.

 

AAA-Ada-boy johnsjj2 !!!

I'll take my hat off to you, cause I know the work involved.
I did that with an AFB though. What a PITA !!!!!

I was thinking about doing my Holley this summer.
Still up in the air. However I was going to try something a little different. I was going to use my drill press, & some milling bits.
I'm still looking for the bits, though

Looks realy good, ohhh and screw the air bleeds. Every book I have says stay away from adjusting or drilling airbleeds, and jet it with (drum roll please) the jets!

Thanks Ron. I would be willing to bet doing that with a drill press would be so much easier. You could control how much you took off much better. If you notice I went through in 2 spots. Had to use the 'ol JB Weld to fix it. The one hole was for the choke rod, the other 2 are on the opposite side. One on top, the other just below going through the side. All is good now though.

 

JB Weld is fine with a carb, in fact thats the best aplication for it.

I used it to mount/glue a vacuum port, that I had to drill into the base. My carb (Holley #9381) is a race only and has no provisions for any vacuum hookups - like my brakes . My intake for the record is a Victor Jr., and also has no tapped holes. It was easier to drill the carb.

Anyways, it looks great. You should of done a tech write up!!!

Aaaaaarrrggggg.........I didn't even think of that!!! When I make my SFC's, I will write one about that if it hasn't been done already.

 

 

Looks good.
Currently mine has no choke tower, but it isn't as smooth as yours...
Might have to do that.....
