So I bought this pickup in November 2018. Immediately realized it needed a new head gasket. Found out it really had a cracked head...
As I was doing forum cruising, I kept coming across a particular build thread(across a few forums) where a Mitsubishi 4d55 was placed in one of these. Turns out it was a mostly bolt on procedure if you found the right parts. So my search was on.
Located the bellhousing I required, as well as an oil pan. Both from an 87 mazda b2600(they ran a Mitsubishi gas engine in those).
Since I now had tracked down the hard-to-find parts, I had to find an engine. I contemplated buying a used JDM import. I looked at a brand new 4d56t crate engine. I was starting to save my $$ because either of those was $3000 to start.
Then this showed up a few hundred miles away. 1985 Dodge Ram 50 with the 4d55t engine.
Got to work pulling the motor. Put the bellhousing on the core transmission I had to test fit it before putting in the Mazda. In doing this, I realized the Mitsubishi-appropriate bellhousing had a 15mm shorter profile than the Mazda. This essentially meant the the input shaft would be 15mm longer.
So what's a guy to do? Initially, I cut the "flange" off the Dodge's transmission and I was going to have it milled down, so it would essentially be a 15mm spacer between the engine and transmission.
After having difficulty finding a machine shop willing to do that for me, I had another bright idea.
I started cutting the back "plate" out of the mazda-appropriate bellhousing so I could use it to a)seal the front of the transmission AND b)use it as a spacer between the transmission and bellhousing.
