This turned out to be tougher job than it looked like at first glance. Even though the motor is very narrow and short and looks tiny on the stand, the narrow vee causes it to be much taller than a traditional 90 degree motor. I had a heck of a time getting it positioned so that it cleared the firewall in the back and cleared the centerlink on the front. There were a few times I ran into an obstacle that I thought was going to stop the whole project cold!
Before I put the motor in I tore it down and did a few modifications. Extensive porting was done to the heads, lower intake manifold and upper intake manifold. That was followed up with a good 3 angle valve job.
I ended up pulling the crank and changing the internal reluctor wheel rather than "adding" one onto the front so that I could run the motor on OBD1 technology. The little motor was in great shape inside with only 28000 miles on it.
Hard to believe I bought it for $180 at the salvage yard. The law of supply and demand at work.
Here is the motor on the stand. Check out the factory roller rockers and canted valves. I should have taken a pic into the port so you could see the straight shot into the intake valve
Here you can see how the oilpan is a structural part of the engine. It is a thick cast aluminum piece and the bolts on the side go straight into the main bearing caps. Inside of it I found a steel crank and cracked PM LS style rods.
Also in this pic you can see how I had to remove the front wheel drive motor mount off of the front of the oil pan.
The 60 degree pulley system I found to work best in the Monza was off of a 3.1 in an 88 camaro. In order to convert the motor to work in a RWD application you have to steal everything from the timing cover forward. None of this is a bolt in but it wasnt too difficult to adapt. A hole needs plugged in the timing cover, Some of the holes in the block need inserts installed in order to accept smaller studs, and the holes in the head are in different locations and need some adapting. In this pic everything is on except for the PS pump. The factory camaro style will not work as it hits the steering box. I bought one with a remote reservoir and am waiting until the motor is in the car before final positioning of it. That big throttle body is off of an Olds Aurora. The 3500 throttle body is fly by wire and will not work for you. I made an adapter in order to install it but the adapters are available commercially. Another piece we fabricated is that water neck you see. Again, if you are not fortunate enough to have access to your own CNC machine, these can be bought on the web.
