67 (YENKO) baldwin motion identification question

[berger]

Hi Jeff, Matt Murphy helped me with cowl and vin they are both off the same straight six, the ss hood was switched for the six's flat other than that they left everything else, From that we were able to confirm she was a ss/rs/bb 4spd, who finally got caught w/ the wrong tags and was lastdriven in80', I'm contacting the dealer who popped her 427 and tranny( the way she set up w/ this monster rear I'm guessing its probably going to involve some sneider race options mated up to the motor, just trying to see if she's an orig 396 or 427.
