Alright, first of all big thank-you to Charlie for all the help with this electronic stuff. Ok starting from the top,first 2 pictures are the tractor when I got it. 3rd picture is the old k301 that I took out, 4th picture is the Identification number on the new to me k321,5th picture shows the exhaust valve stuck in the open position which is the reason it didn't run,6th picture is the engine mounts I welded in for the new engine. This k321 came out of a narrow frame 147 so I had to retro fit it into the 1450. I put a video on YouTube of it running but I don't have the ulr so just type in (Ih Cub Cadet 1450 engine swap) and watch the 47sec video if you wish to. I still have a fair bit of work to do on it but it runs and drives now. I'm hoping to mount a plow on it soon as we already have snow on the ground up here in western NY. Thanks again to everyone for all the replies and help.
