    Holley doesn't recommend a Double Pumper on a car with automatic transmission but so far I haven't had any problems with it.

    Why are thery recommending against it?

    :Do No:

    Good question, perhaps they're afraid people aren't knowledgable enough to tune the accelerator pumps to avoid bog on full throttle. Once I put a double pumper on, I never looked back.

    As usual, they only consider Chivvys. Buicks have their own set of rules:TU:

    Greg Schmelzer What are you looking at?!

    Larry sure got that right!!! I had one on an old 68 Polara I had and never even thought about a different one. Loved it.

    You know why they build Chevrolets? So Buicks have something to eat!

    I guess that's why their rule for calculating the size of the carb isn't working either. :)

    I have a750 cfm DP on my car which according to Holleys rule of thumb for carb size is pretty much the right one but as I understand from other threads I can put on a 1000 cfm without "overdoing" it.

    Thanks for the feedback guys. :)
