    I do know that this particular alternator is correct for a 70 Z/28.

    I thought a 70 Z had a number of 1100837?

    For the Z the alt would have the single groove odd looking pulley on it though. Think you can buy the pulley at some of the Camaro suppliers, Paddock for one.

    1100834 Alternator

    I checked the 1970 Chevrolet by the numbers book and the 834 is a "base" alternator correct in all Chevrolets except the Corvette. It is "not correct" for any high performance motors like the L-78, LS-6 or LT-1 applications. These applications all call for the 1100837 alternator. The "834" would be correct for the 307 and 350 motors (except for the LT-1) without A/C. Information is from page 224. Hope this helps. LT1Z28 Cliff
