Well Don I dont have any solution to this, but humans are creatures of habit and comfort. It seems after Henry 1 died that Ford was reeling from poor leadership. Guys like Robert Mc Namara who thot everyone should drive strictly economy cars worked against the new world that came after WW2. Remember the Mobil economy runs where they used up thousands of gallons of fuel to show how we could save gas ???? In my opinion Ford Motor was competing against all of Gm not just Chevy. So they needed? differentiated engines. And many hve forgotten GM has produced a lot of short sighted engines that were later orphaned. Then there was the idea that putting something like an engine from a chevy into a Ford was one way to have one up and impress people who say those things cant be done. That was a powerful statement in its day, but it dont excite me. And there are some that liken it to cross dressing too. Personally, I always thot this was about having fun and being creative and making friends and memorys.
