BAD engine shaking!!

BAD engine shaking!!
The last time I started my 96 z28, the engine began shaking so hard I thought it would break the motor mounts. The drivers side exhaust manifold smoked a little but that was the only visible problem, besides the lt1 violently moving inches in all directions.
Soo, any ideas?? It has a 5" underdrive pulley kit from the first owner, and has always leaked oil out of everywhere, mainly the rear main. This car was my daily driver until this happened, over a year ago. Anything would help, I'm out of ideas.. Thank you so much, I would love to have this car back on the road!

Could it really cause something that bad, though? My misfire involved at LEAST three cylinders and it was just a mild shake. Could you get us a vid of the shake?
EDIT: Oh, you're talking about crosses wired. HA! Nvm.

I've had misfires codes and a mild vibration with this car since I got it. I fixed the misfires with new plugs and wires, but this is way worse. I am seriously afraid to drive it like this, can I rent a diagnostic tool? And what do you mean crossed? It was fine the day before. Then hopped in the next morning and it was like one of those pay-a-quarter hotel beds. I will get a vid, once I get the battery and valve covers back on.

You could wait until it's very dark outside, open the hood and start it, and see if there's a light show anywhere around the engine.
I've never seen a code reader or scan tool for rent. I realized a long time ago that if you're going to try any work on these that you need a scan tool. I guess you could call Autozone or some other places and see if they rent them.

As for RPM's, it was so bad at idle I didnt want to fool with it too much, but it did get progressively worse up until about 2500rpms, I didn't want to take it much higher.
There was an obd2 scanner on powerblock tv this morning for $70, so I will have to order it.. http://www.summitracing.com/search/P.../?autoview=SKU
I checked and I haven't dropped any valves, but it seems far worse than that.. Do you think it's like a bad rod-end, or a broken main cap or what?

Bad A/C Compressor or Compressor Clutch?
Flywheel weight? (if aftermarket)
When I had a McLeod Street Twin I installed it without the balance weight. That will cause a severe shake/vibration. Luckily You can install it through the inspection plate. So I didn't have to pull the Tranny.
