I am building the 86 302 for the mav. I heard that some of the later model 302's had a reverse flow water pump. Is this true if so should I use the pump on the motor or the one on the 73 doner motor.
The water pump and front engine cover have to be used together. Either way can work, you just have to decide if you want to run V-belt or serpentine. I believe (not sure) that all the reverse drive pumps are on serpentine systems. I am sure that somebody will correct me if I am wrong.
Depends on what application the 86 302 was. The Mustang/van/pickups all had reverse rotation and matching timing covers (the timing cover changeover with the reversed ports started that year) The 79-85 Stangs had reverse rotation pumps that worked with the std rotation timing covers. The 86-91 Crown Vic/Marquis/Lincoln Town Car 5.0's retained the std rotation pumps till the end. The T-Bird/Cougar 5.0 switched to the short reverse pump in 88. The 73 pump will fit an 86 Crown Vic/Marquis/Towncar timing cover only.Not 100% on an 86 T-Bird/Cougar, but probably those too.
the nice thing about the 86 timing cover alot of them had the boss in it still so you can drill the dipstick in for the front sump oil pan (my 87 did) I believe in 1988 they changed to the different front cover. If you want to go to the serpentine system (that gives you a little more horsepower) then that is the front cover you want. Also mine had the boss for the fuel pump with a block off plate cast in it, all I had to do was knock out the plate and I was able to mount an old mechanical fuel pump on the cover.
The 86 cover with the fuel pump boss is the std rotation cover. I've got one of each. None of the revised, reversed port covers had the fuel pump boss.
hmmm the 87 I got has a reverse rotation pump on it but it has the fuel pump boss and I had to drill out the dipstick tube. http://www.latemodelrestoration.com/iwwida.pvx?;item?item_no=M6059D351 1&comp=LRS this cover says it is for a standard rotation pump or a "C50 reverse rotation pump" I know they went to a shorter pump after this . http://www.fordracingparts.com/parts/part_details.asp?PartKeyField=3223 this reverse rotation water pump says it can be used on the older timing covers 1979-1985 with minor modifications? Does anyone know what the modifications are?
The 79-85 Mustang waterpump is reverse rotation, but it fits the std rotation timing cover. In 86, Ford revised the timing cover and pump to improve the flow for the reverse rotation pumps. You have one of the former. The early pumps will bolt up to the reverse 86-93 rotation cover but the gasket surfaces don't mate. This cover was carried on with the 94-97 Pickups and vans. These also used this cover from 86-93. I have pics of both covers in my photobucket site on page two. http://s125.photobucket.com/albums/p53/baddad457/
This is what is throwing me off my motor is out of an 87 t-bird with the standard rotation style cover I am just wondering if the HO motors utilized the other timing cover for the first couple of years or what.
The 86 Stang, pickups and vans used the reversed ported timing cover starting in that model year. If your T-bird had a std rotation pump, it's got a std rotation timing cover too. That would have changed with the 88 T-bird. The 86-01 Crown Vic/Marquis/Town car 5.0's kept the std rotation pump and cover till the end.
No I am trying to tell you that I have a reverse rotation pump with the standard cover as did all of the cars that I have found within that range. That being said you don't find mustangs for that long in junkyards around here (or even 5.0 HO motors) they show up and they are quickly gutted the parts sold on Ebay or whatever and the shells are crushed so I cant compare it to a mustang of the same year.
I see what you're saying. Apparently at some point the T-Birds used the reverse pump/std cover as was used on the 79-85 Mustangs. I know the 84 birds still had the std pump/covers. Lotsa stuff was in transition then.
sorry to resurrect the thread, was wondering, my engine is out of 79 granada, so what type of water pump can i use? and do they make a short neck version? as my pulley sits way to close to the fan.
the only short version of a water pump for ford is the 94/95 mustangs. they have a completly different timeing cover and pump. all bracketery is different. Im not %100 on it being shorter but it looks like it is.
