Re: Cheap serpentine belt setups?
For what it's worth, I'm running the March serpentine conversion kit (#1670) that cost me $185. I also ended up having to buy the March crankshaft pulley spacer in order to get it lined up with the water pump pulley and then move the alternator further out from the engine with longer bolts and shim. It turned out very well and I dont sling the belt anymore.
If you were to go with an electric water pump later, it seems like you could use a shorter belt to run just around the crank and alternator.
It appears in the picture that those are just factory serpentine pulleys. I'm trying to figure out if that water pump pulley has grooves in it or if it is the smooth pulley that comes on reverse-flow water pumps. If it's the smooth pulley, I would be concerned that the belt might slip off at high rpm. If I remember correctly from my '91 5.0, the smooth pulleys are designed to make contact with the backside of the belt, not the grooved side.
