Instead of starting with a factory 396 Camaro (clearly too expensive), Motion went with the lo-buck 327 car to save money and the hassle of removing the SS gas cap and fender SS emblems. Then they swapped in a complete driveline front to back (cheaper than just swapping a 396 for a 427), put "Impala" 427 emblems on it and went racing.

Then let's remove all signs of it being an SS, yank the fender badges, sand off the bumblebee stripe, paint the tail light panel body color, pitch the gas cap and replace it with a standard unit, replace the 396 flags with 427 ones, drop a 427 short block in it, bolt all the old top end stuff back in and then call it an "SS427."

It just doesn't make any sense, and they hardly had to swap the "complete driveline" IMO. 12 bolt was already there, M20 4-speed was there, and the 427 would plop right down in there on the small block frame mounts (it would sit a smidge higher but I doubt they'd care) and with the stock heater box/core in place assuming they even hooked the heater back up in a drag car. Everyone's entitled to their opinion, and speculation is all we have at this point, but I've yet to hear a convincing argument as to why this car was anything but an L30/M20 car at best when it left the lot. Maybe there was an SS396 car there that day, but it must have been hiding behind the grassy knoll.
