You will need a few 86-93 5.0 parts in order to make that work - trust me...
Just changing out the timing cover is NOT going to solve the problem. Sure, it WILL work and allow you to use the old style standard rotation Crown Vic 5.0 water pump BUT ----- once you install the standard rotation Crown Vic 5.0 water pump, you will not be able to align your belt to match any of the other pulleys or remaining accessories.
The stock 94/95 water pump is SHORT, it has a SHORT snout on it and the pulley is completely different from that of the prior 86-93 5.0 water pump pulleys. The stock 86-93 5.0 water pump has a LONG snout on it and uses a different pulley. You cannot interchange the water pump pulleys on a 86-93 to a 94/95 and visa versa. The stock 94/95 crank pulley is FLAT, whereas the stock 86-93 crank pulley sticks out about 3" from the mounting point on the crank... Heck, even the alt pulley or mounting point you may have to mess with...
For returning a 94/95 5.0 to a Fox 5.0 standard water pump your only options are:
86-93 5.0 timing cover
86-93 standard rotation 5.0 water pump (actually a 89 Crown Vic pump)
change Alt. bracket to old 86-93 5.0 bracket
check alt mounting points and pulley to see if it will line up properly
use old style 86-93 5.0 belt tensioner
need a stock 86-93 5.0 standard rotation water pump pulley to work with the Crown Vic pump (or you will need to modify an existing 86-93 5.0 water pump pulley to work)
need a stock 86-93 crank pulley
If keeping the power steering, you may need the 86-93 5.0 power steering bracket as well - but I am not 100% sure on that... because the PS pump on a 94/95 is mounted above the A/C, whereas on the 86-93 5.0, the A/C is mounted above the PS pump.
The 94/95 5.0's are quite different from the 86-93 5.0's as far as the bracket system used, the accessories used & positioning of those accessories and the way the pulleys were designed to work with that 94/95 bracket & accessory system. Everything on the front of the 94/95 engines was redesigned and/or pushed back onto or closer to the front of the engine to clear the new electric fan setup, the new radiator setup, the new A/C lines and cooling overflow bottle, etc...
Research all of the parts first before attempting to tear apart your engine thinking that by just slapping on a timing cover and water pump will do the trick - it won't.
