What Pulley is This One????
Can't find it in any MPCs from 1959 - 1967. It's 7 1/2" diameter, got me stumped. Yah I know, it doesn't take much.

Only pulley i find close to 7 1/2" is 7 27/64" for 1963 421 S.D. engine.
Std 1963-67 are 7 1/4" and Air Conditioning uses 8"+ pulley´s. HTH |

61-62 P8 w/AC is 7 1/2. Non AC is only 7. Both are two groove of the same diameter. The offset is slightly different between AC and non AC. AC then takes another smaller diameter single groove pulley set into the two groove pulley before the damper is put in.

FYI,63SD balancers dont use a bolt on pulley system.They are cast with the groove and the ONLY 2 groove I have ever seen was on McKellers OHC engine.The 421 pass car engines used the bolt on pulley system.Tom
