Hey guys, I have a 83 Hurst/Olds. I love Oldsmobile's, but the engines are not my favorite. I am going to swap my 307 with the LS4 5.3. I just want to confirm some things with you guys. I am going to change the LS4 to carbureted, and buy the timing module with the intake manifold. I bought the engine mounts, but I was wondering about the 200r4 transmission bolting up to the LS4? Am I going to run into any problems? By the way I did take the transmission to a shop and they beefed up my transmission a few years ago. The 5.3 came out of a truck, so I don't know if I need to get an adaptor.
