I have a 670 cfm street avenger carb. I'd like to add one of the bodies to it if possible. They have one for a 750cfm vac secondaries. I know the metering blocks and all would fit BUT i was wondering about the butterflys. I'm assuming that wouldnt work.

I thought maybe there was a way this would work because the body for a 650-750cfm DP are the same...

 

Check out this page and see if you can find your carb number.Proform main body

 

According to that it will not work. It says only the 750 VS....

I just dont see how the DP body could work on a 750cfm and a 650cfm...I know the butterflys are different...

I'm confused.

 

Your baseplate needs to say numbers 172 or 173 on the bottom. I'll send you a word document via pm.

My baseplate is the same as a 600cfm holley I checked that out.

I will pull the street avenger off the shelf at work and see what number it shows.

Id like to be able to use one of the bodies...it would save me a few bucks.

 

They have one body for VS and another for DP.

 

I know but would it work with mine?

The butterfly sizes have to be different don't they?

Only numbers I could find on my baseplate were 11466 and 11469... 11466 is on the top and 11469 was on the bottom.

Butterflys have 109 stamped on them.

 

I said baseplate - the butterflys should be stamped 172/173. The baseplate bores are suppose to be 1 11/16 inch. Like five7kid said, I think the VS have different sizes.

 

Crap it probably won't work then. My butterflys are stamped 109.
