Cs/Wp pulleys LT1

[volquartsen]

Looking for part numbers for Cs/Wp pulleys 1970 Corvette LT1 or any deep groove pulley
that may work, short water pump 1970 Corvette. Never thought it would be this hard to find the
correct pulleys, I see lots of pulleys for sale with many different part numbers stating they are
for 1970 Corvette deep groove just not sure what the correct pulleys are I guess.

Before I drop the money on the pulleys just want to make sure they are correct.

Thanks

I have a brand new GM crank pulley (deep groove) but I forgot the number. Can look later if you're interested. I know it is for a short water pump.

The part number you have listed comes up as
a pulley for BB chevy? Not sure if the info is
correct, I need pulleys for sbc. Or will it work for
sbc? Thanks
