Stan,
No pics handy but I am using
* The 2-pulley damper, looks like yours
* Airtex aw5030 water pump, 292cid 1978-86
* I paid $50, Northern has em on sale right now for $33, good deal
* Housing from 194-230-250, no bypass
* Pulley from 283-194-230 early 1960s single groove
* Pulley groove matches 1st groove in crank, closest to engine
* 4-blade fan is spaced out about 1/4" so it clears the damper but still clears the Nova radiator, it gets pretty tight in there
* Now that you mention it, I did have a heater core leak a couple years ago, I hope I put a big enough hole in the thermostat so the lack of bypass is not overpressuring the heater. Gotta check!
