Rad

If I remember correctly, when I did a roller swap, I had to have the rad shop swap the bottom inlet. I later found out the crown vic water pump has the outlet on the pass side so you don't have to change the rad. Not sure which year the C vic was, but it shouldn't be too hard to research.

 

I would use the 66 water pump. But you can get a "5.0 conversion" radiator that has the lower connection on the LH side.

 

First off, are you keeping the 5.0 EFI or changing it to carb?

If your going EFI, then you'll have to use a 5.0 conversion radiator as mentioned above because of the hose configuration.

If your going carbed, then you can use a regular standard flow water pump and regular radiator because your manifold will change the top hose placement and regular flow water pump will change hose placement and allow the use of the regular radiator.

EFI vs. carb has nothing to do with the water pump. The water pump outlet has everything to do with the FEAD (drive belt system). Mainly, are you using stock brackets and pulleys or aftermarket.

You have a couple of choices. You can use a stock '66 water pump with the stock radiator, provided you are using v-belt pulleys. You can also use the Crown Vic pump with passenger side outlet and v-belt pulleys.

You have to use the driver's side outlet pump for ANY serpentine system that runs the pump in reverse rotation (with the BACK of the belt). Then your options are to either relocate the lower radiator inlet, drop in a "conversion" radiator, or make up or buy a lower hose that goes from the driver's side outlet to passenger side radiator inlet. Ron Morris Performance makes them, or you can get a local muffler shop to make up some tubing, or you can use aftermarket flex hose (rubber or the fancy chrome ribbed stuff).

Depending on motor, EFI motors have reverse rotation water pumps, if he is going to carb he needs a standard rotation water pump which also means he will need to change timing covers as posted above as I'm doing with my conversion now.

The deciding factor is the type of belt system you are using. If you are using the older style v-belt drive, you need a standard rotation water pump with the outlet on the passenger side. If you are using a serpentine belt drive like the "newer" EFI 5.0, you need the reverse rotation water pump with the outlet on the driver side.

You can use a standard rotation water pump with either drivers side or passenger outlet. usually if you are using a 3 bolt balancer (69 and older) you will use a passenger outlet water pump and a Drivers side with the 4 bolt balancer 1970 and newer.

 

I once had a muffler shop make me a crossover pipe which I ran for many, many years. It was my daily driver back in the late 70s. I had planned to do a better upgrade but never did. I wasn't sure of the condition of the 302 or if I would even keep the car, but I kept both. I was in the military at the time and drove that car all over the south east. The muffler shop did a good job with the pipe and it even looked like it belonged.

 

Thanks for all the responses guys but I'm confused.

What I will be installing is a 1980s engine with a edelbrock intake manifold and carb (hose on the manifold is on the passenger side). I am going to be using a v-belt system but one day I hope to switch to serpentine. It's like I'm installing a stock 289, same setup. Should I use a water pump made for a late 60s 302? Does the rotation matter at all? What about the timing marker? (I'm not completely sure that it's on the passenger's side but I thought it was) I think I will be using the 4 bolt balancer but I have to check.

Thanks again everyone.

What side do you want your outlet on? Have you allready bought a radiator or are you using the one that you have? if you are using a 4 bolt balancer you will need conversion pullies to use a passenger side outlet. The length of the water pumps are different. you will install your timing pointer on the opposite side of your outlet. you can use either pump just get the correct pullies and timing pointer to go with it. If I was going to use a 4 bolt balancer I would use a Drivers side Standard rotation pump and buy a radiator for my car with the drivers side lower hose outlet. and use the 1970 style timing pointer. Or If you are using a passenger side lower outlet on the radiator and a 4 bolt balancer you will need the shorter passenger outlet water pump and buy a set of conversion pullies so the belt will align correctlly to the 4 bolt balancer.and use the 1969 and older timing pointer.

 

Conversion rad if keeping pulley set up
If converting to old pulleys, change over to old timing cover and water pump and change to older fan so pulls air instead of pushing through rad.

 

Don't forget 5.0 conversion dampener if going with old pulleys. This will keep 50 ounce balance

 

Can you narrow down the year?..Big difference from 1981-1989...Early 80s would be V belt style and switching to a serpentine setup with reverse pump somewhere around 85...There are differences in the timing cover water ports with some reverse pumps which may not allow you to use a v belt style pump..(look at bottom right side)

 

I'm not exactly sure at the moment what year I will get. I don't have the engine yet but it's going to be in the 1987-1993 range. But it will come without a timing cover anyways, so I need to get that as well.

So what year timing cover should I order? Should I get one from a 68-73 302? It will have a mechanical fuel pump. And If I do get the 68-73 timing cover, would that mean I would need a water pump for 68-73?

How does the rotation effect what pump I should get?

Just get a timing cover from a early 302,351w they will be the same Use a standard rotation water pump and if you are using the stock 5.0L balancer I would use a drivers side outlet and new radiator OR use the passenger side outlet and conversion pullies. just decide what you want and buy the correct setup.

Only if you are referring to stock EFI, which we do not know if he was. The OP seems to be missing some info. I was strictly referring to the type of fuel system, meaning, you can run aftermarket EFI on a stock 289 and still run v-belts and driver's side outlet. That's what I meant by EFI vs. carb has nothing to do with it. You're referring to a type of EFI/engine/year ('86-'93 5.0 HO from a Fox Mustang for example).

 

Gottcha...
