Hello to all my fellow ehtusiats. I am looking for help on a engine swap. I have currently the 307 v-8 with the thm 200 transmission. I am looking for a direct swap on a engine. I dont want to bother with having to weld new mounts etc... I have had my cutlass since 1995. I have had the engine replaced before with the same type and transmission rebuilt also. That was done around in 1996. I have had the same setup since then. I am asking for help or ideas that can help me out on this. In the mean time while I can find the eng I have had problems with my existing eng. Before the winter came the eng started shaking or idleing rough. I would try to accerlate and it seems it just wanted to stall out. I have replaced the plugs, wires cap and rotor and coil. This did not help. Any suggestions on what to look at next? I am looking for a good project to start with my boys (sons) until I find the appropriate drive train. Thank you all in advance for your time and responses.
