The engine has been professionally rebuilt. I don't have a video at this time, but I do have documentation. I am just looking for a ballpark figure as to its worth. Thanks.
Your best place to look for prices on anything is flea-pay for general information. I build my own engines and seldom trust those touted to be professionally rebuilt. I've run into "professional rebuilders" that have never seen a flathead before. They are too different from modern monkey motion engines for some folks to fathom. It's too easy to end up with a rattle can special these days. A krylon overhaul looks good in a photograph.
