I need to find out the GM Part Numbers for the 2 grove crank and water pump pully's that go to an '66 327 CI/350 HP L-79 engine. Can anyone help me out?
The 3770245 W/P pulley is listed as applying to 63-68 327's with special high performance engines, including those with fuel injection.
It is a 7-1/8" O.D., 2-deep groove pulley.
The crank pulley is GM 3858533, the P/S is a cast iron 3 spoke GM 3834720 and the alt is 3829387.
Thank you much for the numbers. Will try my local Chevy dealer first, then the parts vendors.
