A restoration would be putting an Atomic 4 back in with a generator instead of alternator , putting the icebox back in .
You guys are awfully loose with the lingo. I can accept , rebuild , refurbish, renovate, repair , upgrade and modernize , but restore is pretty specific in it's meaning .
You can restore it to 1962 condition , even 1972 condition , but adding an engine that was never offered can't be a restoration .

Unless a restoration is done right , it can lower the value of an object. Any maritime museum would laugh their butts off at this " restoration" .
IMHO #1 has been stripped of her historical value , as if you took the 1st Corvette and replaced the Blue Flame 6 with a 350 V8 .
