The car.............
First impression was a orange 1970 Road Runner with no engine or trans that had been sitting under some pine trees for several years and was encrusted with a green, mossy skin.
Casual inspection revealed some rear 1/4 panel rust through, although not to bad. Areas in the C-pillar and around the rear window that had rusted under the original vinal top, (which thankfully had been pealed off a long time ago). And floor pans that appeared supprisingly solid under a shag carpet. The rockers, fenders and under hood area showed no rust through. I could barely make out the fender tag but could see the sequence on it, the core support and trunk rail all matched.
What kept me from the truth was that the windshield was delaminated and fogged as well as encrusted with moss so that I could not see the dash vin well enough to read it. Add to that the driver door would not open to view the door sticker. Plus the engine call out on the bulge hood was gone.
Further inspection revealed some unusual options. Although the car was a coupe it was really not a stripper...... Options included rocker moldings, hood pins, a factory installed "go wing", vinal top, and factory A/C & automatic trans. Unusual combo I thought.
Heres where one should never assume........! In 1970 on Road Runners.... A/C was listed as not availiable on 440 6bbl and hemi cars..... So that leaves the 383 as the only option with A/C... The U code HP 440 was also not listed as being avaliable except on Superbirds and GTX. Add to that the engine code on the fender tag was E63..... 383. (As was found on the fender tags of all 69 A12 cars).
This all led me to assume it to be originally a 383 car.
