I have a 351w and I'm wondering if there is any way to convert the v-belt pulleys to a serpentine belt. The motor is carbuerated so I'm not sure about the whole reverse rotation water pump thing? Anyone ever do a serpentine belt swap?

 

I am doing it now with the mustang 5.0 hardware. I noticed in the junkyard that the lincoln Mark VII has almost the same setup. I have to lengthen a couple of steel brackets for the windsors wider and taller stance. It is not a big deal though.

I have also seen that the early broncos use the whole assembly from the explorers and mountaineers. I like this set up better, as far as the brackets mount to the heads only. I also like all of the configuration of the a/c, power steering, and alternator. I have posted some questions in the early bronco section to try to gain more knowledge, but so far... no luck.

With the mustang set up I bought a water pump for a 95 F-350 5.8 liter. It works perfect and is the same as the mustang that I got my brackets from.

I found this link from member fungus 232.

what about the water pump? Do you need to change over to reverse rotation?
Will that affect the carbureted engine?

 

you will need a serp brackets, from an 88 5.8 and newer. you will also need the timing cover from the serp engine setup and in which case you will lose your mechanical fuel pump. and yes you will need an 88+ 5.8 water pump as its reverse rotation. this should not affect the carb in any way.

 

Why do you need to change the timing cover? The mustang that my timing cover came from had a mechanical fuel pump with serpentine set up from the factory. The waterpump I bought is reverse rotation.

 

Theres a pic in my garage of my 82 bronco with a carbed 93 351, still has the serp set up, thats a little backwards from the direction you are going, but you could use a donor motor like suggested above. Water pump and fuel pump are the only things that need to be changed as far as I know (and brackets of course). I have an elec fuel pump on mine.

 

Ok, I' a little lost on the timing chain cover and elect. fuel pump?? why do I need elect. fuel pump? And what the difference in timing cover? what specifically does it need to have or not have?
Sorry guys, I just hate messing things up and don't want to do that.

 

All I know is that all of my serpentine set up came from a 1979 mustang 302. It is completely original with 66,000 miles. It was wrecked and has meticulus maintenance records. The timing cover is the same used on my 351 windsor. It also uses the same mechanical fuel pump. I asked for a waterpump for a 79 mustang but they did not have one in stock. I then asked for one from a 93 F-350 5.8 liter. It is the exact same as the 79 mustang but with slightly different internals. I assume that 79 was the first year for the serpentine system and that the reverse flow technology has improved in the newer pumps. If you saw them side by side you could not tell the difference.

I have all of this set up on my motor now and everything lines up.

The explorer set up says the timing cover is shorter and has no mechanical pump location. I think that by having a shorter timing cover, it places the waterpump more center of the radiator. I also do not understand the need for the harmonic balance to change simply for the belt to ride on the pulley.

If the stuff is there in the Junkyard this weekend I will find a carbed 351 windsor and test fit the explorer brackets to the motor. I was hoping someone may have had an answer for us 'cause I am kinda confused.

The older 80's ford truck with 351 windsor have serpentine, but they run two belts. I want one belt. The 90's motors bracket has the tensioner between the alt and pollution pump. I do not see a way to eliminate the pump and get to keep the tensioner.

 

i just installed a serp. sys on my 351 in my 65 i had to get parts from a pickup and a van for everything including a srp timing cover i also installed a 3g alt. and mounted it low and to the right side so i cam install a air/con pump up hi on the right side i don't have any photos right now maybe later

 

What is the difference in the timing cover?

This is my motor with the serpentine mocked up in place.

I just did some checking and I am wrong on my power steering bracket being from the mustang. When I pulled it from the car it had Mark VII written on the a/c compressor with a paint pen. I think the original a/c was the big square compressor with serpentine. I do know that the late 80,s to early 90,s mark VII set up is almost identical to mine. There are some steel brackets that have to be lengthened a little like I said earlier due to the brackets being on a 302 originally.

 

i also am doing a serp conv (302) but using march two belt kit and it says to use a driver side outlet (reverse rotation) pump but they sell a kit for a 289 and it looks the same so i need to mock mine up and see where im at. i have an edelbrock mech fuel pump and they say you cant use them with power steering but i dont see why. ford racing sells a timing cover for like $125 that works with foward and reverse rotation pumps and still has the fuel pump mounting spot. from what i see it looks like one belt uses reverse rotation and two belt setups are standard rotation like the stock v-belt.

 

i looked around and found that the driver side outlet came in foward and reverse rotation. up to early 69 was pasenger outlet standard rotation, late 69 to somewhere in the 80 they still had standard rotation but driver side outlet. then they went to reverse rotation. now if i have a timing cover for a pass side out will the driver side out still fit the timing cover since they both flow the same direction

 

My dad had an 81 302 in his 66 ford with a serpentine setup from a T-bird. He ran it for years with the factory mechanical fuel pump. We always got a waterpump for an 81 t-bird.

 

I went down to the lab (junkyard) and looked over the test engines with the serpentine set ups.

The 80's trucks with a 351 windsor runs two belts with a mechanical fuel pump. It also uses a different looking cast iron waterpump then I am running. The brackets are supported by the waterpump bolts also.

The Explorer 5.0 looks like the power steering pump sits very low on the motor and could interfere with a mechanical fuel pump.

I think I found the total package in a 1989 F-150 2wd with a 351 windsor. The brackets mount and are supported to the heads. They do not attach to the waterpump and use the same waterpump that I have now. You do not need to run the pollution pump to keep tension on the belt either. There is also a pre bent pipe that runs the heater hose to the pump with this assembly. I can also still use the 3g alternator. I will have to change to a different style a/c compressor, but that is no big deal. I will try the powersteering pump bracket with the pump on it tomorrow to see if it clears the fuel pump.
