Where to begin ? Acquire an engine , of course.
I located an engine on that ONLINE auction site , you know who , in Michigan and a 100 dollar winning bid
plus 100 dollars shipping later it was delivered to the local shipping dock.
The fellow who sold it said his uncle worked at a Caddy dealer and removed the engine from a 91 with
500 miles because it was " too noisy" ?
I thought , well it's a gamble but maybe we'll get lucky .
Well , i pulled the rear valve cover and the valve train looked like it came from the
factory , light rust , no sludge , very clean.
So then the front valve cover is pulled,
and we find a mouse has been living there at sometime in the past. {the oil filler cap was missing }
Bits of rags and paper used to make
a nest ,
Cleaned out the top end , pulled the oil pan and flushed everything , to make sure nothing had gotten in the oil pump screen.
While the valve covers and oil pan were off they were bead blasted and powder coated.
We chose COLUMBIA COATINGS
metallic blue with clear top coat for the pan and red metallic with clear coat for the covers.
COLUMBIA has some award winning powders , a very nice selection of hobby and professional guns at very good value. Check them out at WWW.COLUMBIACOATINGS.COM

So the next stop was the local recycle yard for a 4.9 starter. the 4.9 starter bolts to the block.A flex plate had come with the engine, so we attached the starter , a couple cables and a battery.
Cranking the engine without a throttle body installed , 130 -145 psi was seen in all cylinders. Next a 12 " long 3/8 hex rod was inserted in the oil pump and turned with a
drill motor .
55 psi oil pressure was achieved and held for 40 seconds.
At this point it looked like we had a usable engine.
When using the 4.9 starter on the 2.5 transaxle the case must be notched for clearance as in this photo.
This was done with a die grinder equipped with a carbide burr.
In the past it appears most manual shift conversions used a 2.8 Fiero flywheel with holes welded up and then redrilled on the 4.9 bolt hole centers.Below on the left is a 4.9 flexplate , center is an aluminum billet flywheel started with a 2.8 ringear and on the right a stock 2.5 flywheel.
Since we had access to a machine shop we chose to make the billet and use a stock 2.8 clutch plate , pressure plate , and release bearing.
