Does anybody know if there are any differences between the 87-93 5.0 blocks compared to the 94-95 blocks? I found a 94 short block to replace my 91 and am wondering if all my front end accessories and brackets from my 91 will bolt onto the 94. Or would they have change some brackets and mounted a few things differently?

I'm sure the blocks are the same, but the timming cover and all the brackets and accessories are different...

You should be able to just bolt on your 93 stuff...I think "SHADE" is using a 94 Cobra block in his Fox, but I think he converted to an all 94-95 timming cover and pulleys...

Ford make a kit to do this conversion, it's part # M-6670-A50

yeah welcome to hell!

#1 the pulley offset is totally different for 87-93 vs 94-95, so you either use all 94-95 pullies or 87-93 pullies or jury-rig something (shut up )

#2 yeah the above is right, just want to add that you also can not interchange waterpumps and timing covers. 87-93 waterpump only works on 87-93 timing covers, and the same for a 94-95 timing cover.

so basically your choice of water pump/timing cover dictates what accessories you can run.

a 94-95 3G alternator can work pretty well with a 87-93 front dress however, you just have to figure a way to offset the alternator about 3/4", I used washers

Thanks for your reply guys. Well that sounds like what I was afraid of I guess I will continue to keep an eye out for an 87-93 block or just rebuild the one I have so I don't have to swap all my accessories around and figure out how to make things line up.

This is going into an early bronco and there is enough jury rigging stuff around to get this to work to begin with. It would be nice to at least have something bolt on without too much of a hassell or custom fab work

well in your original question, you asked if all your '91 accessories will bolt to the '94 shortblock so the answer is yes (accessories= PS, H20, alt, smog, etc.), just stay all 87-93 or all 94-95 and it's a no-brainer

but I just wanted to point out some of the unique differences

Oh gotcha....yes I do have all my accessories of my 91. I just thought maybe some of the bolt holes had changed or been moved a bit for the accessories, maybe a slightly different water pump that would make it not possible to use the accessories that I have off my 91 on a 94 block. For the time being I am going to use a bi-directional water pump so I don't have to spring for a new radiator. That water pump is compatiable with the 87-93 so it should work fine on the 94 block and allow everything to bolt up.

Sounds like they redesigned some of the mounting of the accessories for 94+, but even though the brackets are different the casting of the block is the same allowing the use of the older serpentine setup. Thanks for the info Joe. Just must have read your post too quick the first time through.

So is that what you like to call toothbrush pieces?
