    Yes the drive/driven gears.

    I have a supplier that gave me the information as to which gears to use.

    But I want the chart to show all combinations.

    I'd appreciate the info.

    I found this chart to go by.

    His discussion is about his Monte Carlo. But a lot is attributed to our "B" body needs.

    Have a good one.

    Well I ended up and put money down on a 700R4 for heavy duty rebuild.

    Mid-Michigan Transmission will be building it.  Tony Martin builds them tough. He is out of Kawkawlin, Michigan.

    A local car show guy has a 468 BBC in a 1968 short box pickup and has not had any problems.

    I had a long talk with him today earlier on the phone and then when I went to his shop.

    He seems very knowledgeable about the needs.  So we will see in a week or so.

    It will have an 1800-2200 rpm stall convertor included.   All for around $1000.00.

    That stall is enough for the XE268 Comps cam w/3.73 gears and 275x60x15 tires.

    Now to take out the old 305 and 350 transmission.   tongue
