I need an upper 3 1/8 keyed 10 rib pulley and a belt along with a lower 2 or 3 groove Vbelt pulley that will work with a blower pulley. I'd also buy any other size blower pulleys if the price is rite or a belt tensioner. Please PM me with anything you have or call or text me at 508-631-4784

I have three new 10 groove belts one is 49-1/2", one is 50", and one is 50-1/2". I bought them as spares, never used them, then sold the engines. $80 each plus $8 shipping.

What were you running them on and what size pulleys did you have?

I had two SBC SC motors with 177 blowers and we had a 174 on the race boat big block until we upped to a Megablower. The 50" went on the 177's, the 49.5 was the stock 174 idler pulley, the 50.5 was the 174 with the upgraded B&M idler pulley.

I have a new 3-7/16 upper pulley, it has the keyway.

Thanks. Do you have the part #'s off the belts?

The 50" is a Bando 10PK1280 (1280 millimeter), I just found the 50.5 is an empty box! Sorry about that. The 49.5 is a Gates K100495.

Just ordered 2 new belts today. I still desperately need a 3 1/8 upper 10 rib keyed pulley!!!!
