Anybody put a LA Mopar in an AMC Gremlin?

With your initial post, I saw the word "budget" and thought you just wanted to have some cheap fun on the track. That's why I suggested the AMC 360 & TorqueCommand (easy to install and get underway). Now that I see all of the other components and plans you have listed, you might as well just use what you have and be done with it. Start building & fabricating. GL.
