Engine Choices: What interests you the most?

Nothing that really belongs in an A body. The older I get, the more I like the obscure and unusual. I guess it's the rat rod thing I like so much. Like International gas V8 engines. Kinda always wanted to put a 549 in something. And the GMC 702 V12. The more obscure the better.

Would be cool, but need to stay true to Mopar and not build anything that's to Frankenstein. Need to be allowed on the drag strip! Lol.
