Pulley part number help

[jasonL78]

Have 3 pulleys that I thought were off a 70 LT1 350. Anyone out there know what they fit.

Crank# 3850838BG
power steering extension# 375123
water pump# 3890419ct


Thanks Jason

Thank you I think I am missing a number on the extension it might be 3751232. They were on my 70 nova and it had a short water pump. The guy I bought the car from said the motor was from a 70 corvette. I see they are not worth much I may just hold onto them.

That makes more sense.
That #3751232 is a Crankshaft pulley used on just about every Chevrolet Small block application with Power steering & w/ & w/o A/C from 1959-1969.
Used on Corvettes-Series 10 & 20 Trucks-Big Passenger-Chevy II-Camaro-Chevelle.
I agree,I don't think any of these are that sought after or hard to obtain.
