    Street or strip?

    what t-ram? The plemum size will have alot to say about the carb you pick.

    you can also go EZEFI - i did it on my t-ram & its a blast!

    I had the same set-up on my old 426. Worked great. That would be my recommendation. Two - 660 center squirters....:glasses7:

    the 660's are fun, but i'd still prefer a vac secondary for a street car.

    I heard Holley made the 660 specific for tunnel ram setups.

    I think Edelbrock makes a set of 500's set up for dual carb installations. A pair of small vac secondary Holleys (1850) are popular choices too.

    I read in an old Dodge engine book about running the 660 center squirters and changing the rear metering plate to a block with jets........keep the thoughts coming.
    thanks,

    try 2 of the cheapo 600, 650, 700 or 750, vac carbs. the 600 and the 650's you can put on parallel to the t-ram (simple linkage) and the 700 and 750 have to go sideways.

    You say street/strip......How much street?......I would consider the 660's a very limited street carb at best.

    Just keep in mind that they come with a pretty rich fuel curve. On the R4224, the primary jet and secondary plate are both #76 jetting from Holley and that's pretty fat for that size carb. Also, the secondary openings are 1 to 1 with the primaries.


    P.S. On the plus side, the MP .528" cam is pretty mild for your cubes and head flow. I could see 10+" of vacuum with that cam when everything is tuned right, and that's a big plus for streetability with the 2x4's.

    I have ran both, the mechanicals are best for the track and the vacuum sec. best for the street.
