Shp 327 smog pump pulley

[Jeff P.]

GREETINGS,

Does someone no if the Deep Groove Pulley used on the Big Block smog pumps, was this also used on the 327 Special Hi-Performance Engines with Deep Groove Pulleys on the water pump , crankshaft and alternator ??? This engine used alot of hi-performance parts just as the Big Block engines did. This is a 1968 HT engine code. Thanks in advance.

The SHP small block and the big block AIR pullies were NOT the same. For 1968, I believe the small block pulley for both 300 HP and L-79 was GM #3817234. For 1969, I believe the L-46 used pulley GM #3932458, although it's possible, I suppose, that some or all 1968 L-79 also used this pulley. The big block pulley was GM #3925522 for both 1968 and 1969.
