Ok so this project will seem pretty simple compared to what you guys are doing but it is the first time I am attempting something like that and I am very very slow. I hope I will be done by next summer.
Anyways I will try to post pictures and explain what I did, just in case some novice guy like me tries it also.
The engine has some miles on it and is not very clean (1999 with about 150k miles), it was used in the rust belt. But if it works I'll be happy. If it doesn't then pretty much everything will be done by the time I will find out and then I will have to look for something more recent.
So the first time I did is modify the electrical harness by following the instructions found around here. The problem I ran into was that the harness has been cut right behind the engine, I had to resolder all those wire. I hope it will work!
My second problem was how to install the engine. My Caddy had the Olds 307 engine so different engine support than the Chevy engines. Being on a tight budget I decided to try using the original mounts and adapt them to use them on the 4.8 engine.
Third problem is that I did not have a proper engine hoist, just a hoist that goes up and down.
So I made a template out of plywood that mimics the shape of the cross member under the engine. I also drilled two holes so I know where the engine bolts should be placed.
I decided to keep the same distance from the engine brackets to the transmission-mating surface at the rear of the engine. It puts it very close to the firewall, I hope my transmission will fit.
Vertically I used the template to try and make sure the oil pan won't touch the cross member.
Horizontally, I found out the supports of the crossmember were not symmetrical so another calculation needs to be done there. I tried to place the center of the crankshaft pulley (or flywheel), at the same position as with the old engine.
Anyways here's a few pics of the mounts I did using the template drawing I found for the S&P style mounts. I joined that plate to the original (Oldsmobile) engine brackets with a 2"x2" sq tube.
Here are a few pics showing how the engine is positioned. Keep in mind it is not at the right angle yet. When I put the transmission it will be tilted more rearwards. I was afraid it will interfere with the steering damper. It doesn't
That's where it is as of today.
