1995 3.8 non supercharged Riviera cuts off randomly

Ok ive replaced the ignition module with a ac delco unit, replaced the ecm, replaced the cam and crank sensor, all in a attempt to stop my riviera from randomly shutting off, usually as i stop but sometimes while driving, will usually crank right back up but sometimes have to wait hours before it will restart..any ideas ?

SOURCE: wanna know if i can put a tranny for basic 1995 riviera in my Supercharger

you will most probably need a beefed up tranny to take the power of the engine, I have just installed a 350 supercharged chevy motor in my sons car with a Turbo 350 transmission and a shift kit which I have been told by an auto trans mechanic may not take the power of that engine.
It is costing him $1500 australian to have it reconditioned so I hope it will survive the rides

We have a 95 buick riviera with the supercharge 3800 v6 engine. It overheated, usually runs at 200 degrees and blew the oil dipstick up and oil splattered on the engine. Oil level is ok and oil...

The overheating might be caused by a thermostat stuck closed, have it replaced. That should fix the overheating, as for the hesitating, run a scan on the ECM module to make sure you dont have any codes, clear if any and fix anything that might've gotten damaged from the overheating.

I would install a new fuel filter. You might want to replace the spark plugs and wires at the same time. I would install a new fuel filter and see how it runs.

You should also swap the transmission if the motor is going to be more powerful. Also a new computer will be needed for the swap. If you are looking for an easy swap then just find the same motor.
