Does anyone have info on this alternator? For what model, etc? Or a casting numbers link? Has double pulley, 37 Amp. Thanks.

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

I thought a 70 Z had a number of 1100837?

Tom the 70-71 Z and 70 L78 uses the $$ 837 $$

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.

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
