Deuce is right, V8. Just a thought to confuse the issue, if it is really a Wescott body, why not buy new doors from them if yours are really bad? That might solve your prob. less expensively and allow you to continue to drive your car. I like the history you have found, and maybe you could find out how old your (roadster) body is and have a kool historical ride. Wescott advertises their first body as still being on the road.
