Motion Performance Holley Gear Drive

[DAVE H]

I am not familiar with this "kit" from B/M but, I have the 2 baseplates in the pics. There is quite a bit to dig through in unorganized totes full of Holley carbs and carb parts. Is there anything specifically related to this gear kit I should be looking for?
Thanks for the help,
Dave

I've got one of those kits. Normally they come with another "Y" shaped metal piece that essentially made a single pumper into a double pumper and opened all 4 barrels at the same time via the gears. Not sure how effectively they worked in real life. Once double pumpers came out in 1969, no need for them.

Pump nozzle and pump cam was also included in the kit.

there were a few companies that sold the conversion kit such as Mr Gasket.
Some people also added the large Holley accelerator pump when they installed the kit

I found these 2 carb bodies with the secondary squirters.
