Now just to play the other side... There is a roadster that attends shows in my neighborhood running an old Buick straight eight. That guy has a supercharger on his.
I don't know if the bearings are babbit or insert in that motor but I do know it has a VERY long crankshaft that would give me the same kind of worries the 216 with babbit give me.
Maybe we should ask what you really expect from this turbo motor?
Are you expecting some turbo whine and 'oh wows!' at the shows or are you expecting to push the horsepower way up. If the turbo is more for show than push maybe its a doable idea after all.
I don't like raining on anyone else's parade but unfortunately I find myself doing it all too often. Somehow I turn curmudgeon when I get on the Internet... Tell us a little more about your intentions. We might come back again with even more caution or might chuckle and say we want to see the pictures and watch the build.
