Based on some super helpful historical data obtained from Dave Pateman, we now know that the original engine for this car was 6404202.
It looks like it was sold on The Samba in February of 2018 for $2700? The seller was zsvendschmidt of Newport Beach. He appears to have a car business called Newport Classics. I have tried to contact him several times via email, phone, text, and Twitter. He never replies. Maybe I will try stopping by there when I’m in SoCal next. If he’s a car guy, you’d think he’d want to help reunite an original engine with its chassis. I just don’t understand people some times…
