It looks like you are good to use any GM engine. Before you buy one, I would crawl under there and verify that you do have the dual bolt pattern on the trans, but it looks pretty promising. Your stock trans was only built to take 200 horsepower, so you will eventually need to rebuild it, but it will last a while. Just depends how bad you beat on it. The 200R4's can be built to take a lot more power.
What to put in my Regal?

Maybe ask this in the GN forum here, but were the 200-4R's in the GN's "built-up"?? Because they were rated at a very conservative 245HP but we all know the real number is at or above 300.
Just a thought, as far as how much power a stock 200-4R will handle.

Ahhhh... way more. Leave it to a trans. shop or buy a trans already made for the power. But, it's not cheap. $1200 for a 200-4R plus you'd still have to buy a converter, another $300
I know you don't want to give up the OD, but either run your 200 'till it dies or find a TH350. With 3.42's for rear gears the RPMS will be around 2400 @55MPH which isn't terrible.

The 200-4Rs that came in the GN/Ttype/442/MCSS did have some better parts valve bodies servos factory shift kit. They had different shift points even shifted in OD at WOT. That said they are still somewhat weak against brute torque but usually what breaks behind a small block does not ruin your day. A GOOD shiftkit such as what CKPerformance makes and a large cheap transmission cooler will help alot with helping them hold up without breaking the bank.
