Engine Swap

Yes. You just have to use the timing cover and accessory brackets from you original 95 motor

They'll both physically fit. The 81 is carbureted and the 90 is efi. If you're looking for something to "drop in and go" the '90 will be the best bet. I'm not 100% but you might need a new wiring harness.
Good link on the specs by year.

Quick question. How many miles are on the engines being sold and how much are they asking for them? For around $2k you could have your old tired one rebuilt. It'd run like new or better and it'd last you another 300k mi.
*Edit* If having yours rebuilt is a no go, I'd still pass on both of those motors. Search for a 5.0 Ford Explorer motor. More bang for the buck.
Take a pass on the 81

Again with incorrect information.

The "302" block has never really changed. It's 100% interchangeable thru all years. The short blocks are no different other then the strength of the block. Boss, Mexican, and frpp blocks are stronger.

No harness change, no nothing. The only downfall to the older blocks is no forged crank but since he didn't mention plans on boosting right now it doesn't matter.

Quick question related to this though. Since he mentioned getting the exploder 5.0, were they OBDII, so you could in theory switch to that computer with more up-to-date tuning software?

I think I remember someone on here running the explorer 5.0 with a really nice build. Mika I believe?

 

Explorer 5.0 was obd2 in the explorer only cause it has a timing sensor in place of the distributor. To do the same in the mustang you have to go standalone with individual coils.

You can use the exploder motor with your distributor tho and it's fine.

The way he worded it made me believe that he was looking for an engine to drop in and run. He didn't say he was looking for a shortblock to rebuild. He said, "I'm looking for an engine to replace the tired one in my 95." So I assumed he was looking for a running engine. Which if is the case how much "less tired" could an '81 be anyway? So I'm wrong about the '81 being carbureted? Yes he could swap over the efi stuff from his I guess.
If he's looking for a motor to drop in and or rebuild wouldn't you start with one that has the better set of heads and intake? Out of the box the '81 is slow as dogsht
OP: if you're looking for a motor to rebuild then why not rebuild yours?

You'd also the engine wiring harness from the exploder too. Then convert the guage cluster to the OBD2 computer.

 

He'd probably want a cam and valvetrain upgrade too.

Which firing order did the 81 come with? 1-3-7-2-6-5-4-8 or 1-5-4-2-6-3-7-8

 

Yep, ol'boy is gonna need a mustang 5.0l or a 302 with the "HO"(high output) camshaft, better known as a 351camshaft

 

Yeah yeah he could stab in his cam from his 95. You know you'd throw in at least an alphabet cam or the likes if you had one torn apart.

I think night train has left the station...

Op where are you located?!???

So you get coils, wiring harness, and a computer and you could have an OBDII 5.0? Neat, thanks for that guys!

 

stop giving tech advice.

 

That would be a good start and then think it thru on what you really want to do so you don't end up like me with my 1st time doing it and trust me I've gotten enough to fill a pool hahaha,deffenitly a learning experience.

 

Gears are the best bang for the buck.
Headers and full exhaust, CAI, and bigger TB will only provide minimal HP gains.
Another popular budget upgrade is explorer heads and intake.
