302 info requested
Needing a 302 for my 1989, what other years or other vehicles did the same engine come in? I dont want to change the wiring harness if I dont have too.
Thanks in advance.

They made the 302 from, I believe, 1968 - 1996. I think around ‘87 you could get a roller camshaft block. You would reuse your timing cover so the fuel pump hole and regular or reverse rotation water pump wouldn’t be an issue.

Any Ford Windsor 302 will fit and bolt up, but you will have swap parts like intake, timing cover, etc. so it will work with your existing setup. Donor wiring is irrelevant as you will only use what is in the 89.
I would advise you to find a 302 out of a 94 - 96 truck or bronco so you will have a roller motor that will just drop in with no need to swap anything. Other than that I would focus on engines with E7 heads or GT40 heads, anything else will be a step backwards.
The 302 was available in Explorers and Mountaineers until the early 2000's but the later models will have GT40P heads which will not work with your exhaust manifolds.
Rebuilt long blocks are still available from Ford and are relatively inexpensive considering the warranty. Flat tappet cam engines are cheaper than the roller cam engines, and if I was going through the trouble of swapping an engine I wouldn't want to do it twice.

Any ford 302 from a speed density EFi truck or bronco would be 100% plug and play.
A ford 302 from a mass air EFi truck or bronco would require you to swap the lower intake.

That is a fair point, and I will edit my previous post.
I would refine your point to say that a 302 from a mass air truck or bronco is not 100% plug and play, as you would need to swap the lower intake manifold. Any Ford 302 from a speed density EFI truck or bronco would be 100% plug and play.
However, I would still recommend a 94+ roller motor from a truck or bronco.

The only motor that would be 100% plug and play with no changes whatsoever would be another '89 truck motor because that is the only year where the engine wiring harness will match perfectly. For any other year the harness has to be transplanted from the old motor, '92+ engines had a roller cam and the ignition module was moved to the fender so the old distributor must be used with a steel gear swapped on, and if a car 5.0 is used the upper and lower intake, oil pan and pickup must be swapped along with accessory brackets. An Explorer motor could also be used but it would have to be stripped to the bare longblock and everything from the old motor put on it. All of these options are more than doable so my advice is get the lowest milage 5.0 you can find and make it work.
