Alternator pulley grow Q

[Mikke H]

The alternator pulley on a 1970 Six Pack Bbody was it single or dubble grow ?

I believe it would be a single groove as a/c was not an option on the six pack engines.

ABSOLUTELY CORRECT.....I too have a 1970 GTX, RS23V0A******, and it equipped with a 37 amp, single groove sheave. (Which I've up graded to 60 amp by changing the stator windings and diodes but looks origional)....and the amp meter has NOT exploded or caught on fire.....
