I got an underdrive crank pulley from The Donk and I'm just wondering what size belt I need to get or if I can use the stock belt.

This is the CRANK pulley only, no water pump.

I have Steedas and used the stock belt.

No, I used the Steeda water pump pulley. I changed out my water pump as well at that time.

You will need a belt that is 2 in. shorter when using the crank pully only. If I can find the part # I will post it.

Why dont you slap the original belt on there and pinch the belt until the idler is where you want it.

The Marauder is the parts runner car....

Anyone else have an idea of what belt to get? What size? From what I see the MM's is a 93"

Okay, Just got done reading some OLD threads from 04'ish. Looks like the Electric WP has the stock pulley for its idler. With the steeda underdrive folks are running a 90.5" belt.

My research wrong?
