The rear butterflies have just been coverter to one single flap. Just make sure it will work on your intake. That rear door night get hung up on a standard 4 hole or dual plane intake.

It had revised secondary metering to fix a lean tip in stumble on the smaller 950. Most of the early intakes were already notched to clear the butterfly. 4553582-CH4B.jpg (148 downloads) `02 RAM2500 SPORT V10 4x4 `06 GMC sierra NO cars

They`re 3160 carbs so the secondary side has a metering plate with drilled jets like all the 60 series holleys and you can NOT swap it over to a metering block because the booster feeds are closer together than the four barrels. `02 RAM2500 SPORT V10 4x4 `06 GMC sierra NO cars

I dont think these parts are made anymore but if you can find them they do work. Im going to go through this one and put it back in service soon. Take the vacume pod off, add the gears to the linkage and the accelerator pump nozzels to the rear. 4554787-estimate116(Small).jpg (230 downloads) 1969 Hemi Roadrunner 2nd owner

Those gears look to be 1:1, so im sure a simple linkage could be made to do the same thing in place of the gears.

Did find a really great small block bracket carb I forgot I had though, a 780 vacuum secondary double pumper. I think they only made these for a little over a year sometime in the mid 70s. 65 Belvedere II Station Wagon 69 Coronet R/T convertible 70 GTX 70'cuda 99 Dodge Diesel dually 4X4

I still have a Car Craft mag from around 1970 where they took a Baldwin Motion 69 Camaro with their warmed over 427 with headers and did a swap from a 780 vac Holley to the 3 barrel carb that was an 850 I believe and it went from 11.90's to 11.60's. That carb was used a good bit back in the 70's and worked good. Ron

When used on a single plane, X-style intake the 3rd cylinder back on each side, (5 & 6), tend to run on the lean side unless there is at least 2" of spacer under the carb... Someday I'll learn how to type and hit the right keys ... not. Last edited by rmcomprandy; 07/19/08 11:28 AM.
