An '83 307? Do you mean 305? I have the opposite problem. I have a tub full of pulleys and don't know what any are off of. I may have what you need but have no idea.

Re: pics and part numbers

Parts books don't list as short pump, narrow balancer, '83 307, etc. I understand that you're mixing things up.

However, best that I can come up with is;

for water pump:
#3900434 - All w/dual belts & pulleys, 2 grooves. (supercedes #3790356)
#3905995 - All, 1 groove, 7 1/8 OD x 5 3/4 ID. (supercedes #3788472)

for the crankshaft:
#3755820 - V8, single groove
#3923898 - 2 groove

These numbers may/should be stamped on the pulleys, good luck searching.
