B&M 420 Mega Blower Pullies
 

I need two... I'll get measurements...

Mine are stock from the 600SC... I'm looking for smaller ones...

I think the ones from the 800 SC were a bit smaller...


Update. Mine are 5.0 so looking for something under 5 inches.

I have two 5.375" pullies that I bought from teague and used once

Let me double check the size

Correction they're 5.9" from the blower shop. I replaced them with the 5.375s. Still in the boxes they came in

Are you looking for the upper or lower pullies? I have a few upper ones but I need a lower..

I'm looking for upper pullies. Mine are 5.0. I need something a little smaller.

Are those lower or upper pullies Rbesola. How big are the opposites?

Those numbers seem big. I'll have to measure my lowers. There at the engine builder. My lower look to be one piece with the v groove for the water pump.

Can you let me know how big they are? Sorry can help you with lowers.

Up up

i have a pair of lowers fora stock 600sc with v-belts..

You are looking for 10 rib pulleys. Rbesola has 16 rib pulleys.

Tough call on what to do there.

You may be able to buy a traditional triple vee groove pulley, like you would use on an 8-71 blower. Then find another set of 600sc top pulleys, but mount them on the bottom. This would change your current ratio from .93:1, to 1:1. That should net about 2 more psi than what you have now.

Sorry for the delay in responding. The upper ones I have are 16 rib part numbers are 155174..8901568..155172..155175
