Hello everyone! Just joined the forum. My name is Jamie and I live Brainerd, Mn. Purchased a 78 Trans Am at a Mecum auction last year and just starting to get around to restoring it. Its a mess! Any way it is a W72-6.6 litre t/a(400) 4bbl V8 with auto transmission. Nothing I can find out on WS6 or SE that I can find. It is numbers matching. It has a cool mis stamp (same#'s)on the block like a rare coin. It was shipped to Bill McDavid Pontiac dealership Jan. 9th, 1978.
Being its not a SE, trying to decide on the true decals for it. It is starlight black, 19L19U19B1 interior codes, C60-factory air,
K30-cruise control, Y90-custom trim group-velour, A31-pw, AU3-power locks,BS1-additional acoustical insulation,WW7-Hood decal, YJ8-cast aluminum wheels,N33-steering wheel tilt,etc.
Btw, this is a great site for the information, Thanks!
