So I have A 94 Ranger with a 90TM-AB 4.0L V6 in it with 176,000Miles.

My Autotech teacher has a 90TM-AA 4.0L V6 with less than 100,000Miles from A rollover victim 95 Explorer For $100 bucks. It ran perfect when they pulled it 4 years ago.

I want to get it as a replacement engine for my ranger but I'm notsure It the casing numbers make A difference and if it will work with my electronics.

Would It be worth the hundred bucks?

What are the pros and cons of the AA and AB Blocks?

How hard is the swap?
 
I got the engine home and read the casting as an AB motor. so never mind
