I am selling my March Serpentine pulley kit. It's for a small block with short water pump, No A/C (which makes it standard rotation WP), power steering, alt, crank, WP pulleys. This was on my car for a few years, ran great. I just upgraded to AC. Includes all of the shims you may (will) need, belt, Stewart Stage 2 short water pump (used), and other options.
Let's talk - IF it's going on your Chevelle, you need the remote power steering pump brackets/kit, I have that.
If it's going on a Nova/Camaro, you could use the saginaw power steering bracket/pulley, I also have this.
I have the pulley for a 10SI alt, but have a CS144 that was bead blasted and clear coated. I ran the CS144 on mine for the last few years.

Example of new kit:

This is Priced OR best offer. PM me if you have questions or want more photos.
I will ship, but I can guarantee this will cost at least $100 to ship, it's heavy. If you want me to ship, I'll charge actual UPS numbers.
