AMC 401 engine for my 1972 Duster

Get out the welder and have at it! So what... I have seen Ford engines in everything. A 350 Chevy engine has been installed in anything you can think of. The Hemi has been the go to drag race engine in every car for years. Rat rods have no rules. I have had a few very good running AMC cars as well. So I don't see what the problem would be. It's not like your cutting up a Hemi Cuda. Sure Chrysler bought AMC and then used them up but they were dead anyway and if they didn't what would have happened to Jeep! Who knows? AMC used the Chrysler transmission so it counts in my book :-) Just keep them running. I love seeing the AMC stuff at car shows. Don't see very many anymore. Makes me said, I worked at a dealer back in the day and the Javelin was a runner. So was "The Machine". Gremlin X 304 was no baby either but the big three got the lime light. Have fun with it, that's what it all about :-)
