In the old days, we would swap engines in anything. It didn't have to make sense. We put a Cadillac engine in a 50 Mercury. But, now the Cadillac had no engine, so we put the mercury flathead in it. Talk about a slug! But, as I have gotten old, practicality has taken over... maybe too much. Except when it comes to buying cars. I wish it worked better there!More horsepower does give more ET flexibility. Fuel injection adds flexibility.
Not necessary though, you’re correct. Definitely more fun.
