I have a 1949 Ford F1, frame off restoration one year ago.
The truck looks wonderful (show condition) though the original Flathead 239 cy
V8 starts well, runs for an hour, then stalls and hard to restart. Can't find a
competent mechanic in N. FL. So frustrated I am considering new, up to date
engine though as a purist, hate to change my original equipment. Would new
engine harm value of the stock truck?
