Cheap serpentine belt setups?

Anyone convert an older style 289-351 with v-belts to a serpentine setup?..I know march makes a setup but I don't want to spend a fortune doing it as I may go to an electric water pump down the road...I have no power steering so just have to run the alternator and water pump....I also want to keep the standard rotation pump so I don't have to change my timing cover(although I don't mind changing the water pump).....What I am looking for a setup similar to this.

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.

Re: Cheap serpentine belt setups?

kgordonl Do you have any pics of your setup?...I agree the picture I posted appears to have the smooth pulley on the water pump and I wouldn't trust it at high rpms..I just put up the picture as a reference to the basic setup I was looking for..

As soon as I get the car back here to the house (probably Monday) I'll be glad to snap a few pics and post them. It's getting the electric vacuum pump installed right now.
We are using a factory electric air pump off of a '96 Impala. The guy installing it used the same set up and perfected it on his late model Mustang that has a nearly 1000 HP five hundred and something cubic inch big block. The GM vacuum pump is light, compact, and inexpensive. He drills the internal plate to make the appropriate vacuum, welds a bracket on the frame, and just wires it up. Then he runs the vacuum off of the valve cover, to the pump, and then out to a "catch can" with a breather. I'm looking forward to seeing how well this works.

I used stock Ford parts. I bought some used parts and have less than $50 in the hardware. I did get pulleys from Mustangs, T birds, etc. I switched since I actually wanted to add AC. I originally had the pass side lower hose and that is a big change. That means the timing pointer is cast in. You can use the reverse rotation pump with no problem. I switched since it seemed to open up the possibilities. So I have a 70's cover with a 84 or so Mustang drive. I drilled a hole to change the tensioner position to eliminate the smog pump and PS.

Re: Cheap serpentine belt setups?

Iwantmore can you explain how you got the reverse rotation pump to work on the old style cover?..There seems to be a lot of confusion as to whether you can do this or not?...In this picture that I borrowed from the sbftech site (courtousy of JOEL5.0) you can see the bottom two timing covers have radically different ports (standard rotation vs reverse rotation)and it doesn't look like it would be possible to get the water pump to even seal up?..

Re: Cheap serpentine belt setups?

Take a look at a mid-80's Crown Victoria with a 302. It has serpentine belts with a grooved water pump pulley and standard rotation water pump. You might need to switch to a late 4 bolt balancer to get the right spacing; not sure about this. A 351W would have the right 28 oz. weight for a 289 or early 302.

It's kind of a tight spot to get a good picture because of the fan shroud, but here's what I got...

Re: Cheap serpentine belt setups?

I originally remember looking at 60 70 and 80's covers that I had in my hands. I do not remember problems with the water pump mating up since I used standard and reverse on the same cover. The problems were every where else like dipstick, timing pointer, or fuel pump. I actually cut off the timing pointer on a mid 60's cover so it would clear the newer pumps. One cover in those pictures that is different is for a 351 I think.
