300i6 interchange question
Hello, all. Well my '85 has decided she's got no more interest in life. (Only 90k miles, but the PO seized it .. twice, apparently).
My plan was to take and overhaul a second engine and then put it in. Well that's likely not going to happen. I have a running 1983 engine that I plan to put in over the next few days. Meanwhile the old girl is soldiering on as a Ford I4-1/2.
While its on the stand I'm going through it all just to be sure. Gaskets, etc.
Motor mounts on mine could stand to be replaced after all this vibration. I see 80-84 listed, then 85-89. They do look a little different.
Will the 83 engine fit the 85 mounts? It looks to me like its the actual frame end of the mount that has changed. Not the engine side.
Just trying to get my ducks in a row here.
Thanks as always!

I'm no expert, but as far as I know the blocks are the same. My truck is an '82 and my 300 6 block is a 95/96. So it would be the perches/crossmember side. I'd order the ones for your year model, unless someone jumps in here and says otherwise. I have a feeling @pmuller can explain the differences.

There's not really any noticable differences over the years. I've had 4 engines between 80 and 88 and the only difference is the fuel pump boss doesn't have a hole for a mechanical fuel pump on the efi ones. Motor mounts should be the same on all of them I imagine.
