aerostar 4.0 in explorer, will it work?

[Blacksmith1]

The explorer is a 94, the Aerostar is a 92. Both are 4.0. I remember reading on this forum a few years ago that the opinion was there was some differences that would be an issue. I'm thinking that if I use the bare engine from my van and all the under hood goodies from the explorer it should work.
Am I wrong?

After finding the 4.0 information in the tech articles it appears that these 2 engines are the exact same blocks. so problem solved.

I have a question about these blocks. the 92 A-star motor has a drive for the oil pump where the distributor used to be on the old 2.8, 2.9 blocks. the explorer has a camshaft position sensor mounted there. is it safe to assume that the 92 models did not use this? Something ford added for emissions or economy? I'm going to put a new one in since I kinda gutted the old one on the firewall pulling the engine but I'd really like to know why one has it and the other doesn't.

The purpose of the Cam position sensor is to time injector pulses on a SEFI engine,

A '92 doesn't need this some 1993's and most 1994's do need this...

But what you are proposing IS possible, do be aware that the biggest differences in
the Aerostar 4.0 engine are the Exhaust manifolds. Most of the other things being
discussed here model year differences, ot production date differences.

BUT not all chassis instituted changes at the same time...
