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.
GM may still carry these as well as LICS.

Scott;
Thank you much for the numbers. Will try my local Chevy dealer first, then the parts vendors.
