Underdrive pulleys
 

I bought BBK underdrive pulleys but the water pump doesn't have groves. I don't have A/C or power steering. The that wouldn't work for me. What brand of underdrive pulleys have the groves on the water pump pulley.

I don't think any of them do...5.0's are never set up with that belt routing and the water pumps are reverse rotation. You'll have to get an A/C delete kit...

Well, I guess I'm going to take these pulleys I got to my friend and get him to machine groves in it for me.

I wouldn't do that. The 5.0 motor, with or with out A/C andPS are set up to run a reverse rotation waterpump. That is because the belt coming off of the crank wouldn't have the friction, and under load it would slip...by making an "S" from the crank to the Waterpump, it "bites" the pulley harder...I wouldn't machine grooves...

its not a current 5.0 water pump. It not the reverse rotation water pump.
