Correct Crank Pulley Fit for 69 Big Block A/C?

I just put a 427 in my 69. It has a/c and the pulley is 3 groove from a Chevelle PN 3937787 AC. There's hardly any room between the outernmost groove and lower cross support. The belt may even be able to rub once installed. I used the correct frame and motor mounts... Is the Camaro pulley typically smaller or the same as the Chevelle? It measure 7-11/16 inches across the diameter.

Mine is real close and is the correct one. It is hard to get the belt on but does not rub.

I believe the Chevelle, Camaro and Corvette pully's are all the same. I run one in a 70Z BB and it's tight.

Accroding to Jerry McNeishs' book, the 787 pulley is not right for a '69 car. I can't remember the correct pulley number off the top of my head, but I'll look it up later when I get home.

Experience...... It's what you get when you didn't get what you wanted.

Know mine is a BB 68 Camaro wth a/c (short water pump), but the diameter of the third a/c pulley is 6 3/4".
Plenty of clearance to the crossmember. Correct pulleys per CRG. You could go there for your correct 69 a/c pulley numbers.
