Not typical engine stamp. The rear is coded QL which decodes to 331 non posi and trans stamp should start with P = Muncie 7 = year or P7 which it doesn't, and no claims of originality of drivetrain.

This 323 from a '67 Chevelle was cast F 8 7 and stamped T0630 same as Steve's L78. Any known 323's cast/built earlier than these??

Steve is 4 bolt Chevelle is 2 bolt which means nothing but info.

Hmmm 🤔, got me thinking about my rear end housing code stuff. I remember Mike S. telling me he got the rear from Bob Harris. The ring n pinion is 3:73.Get back later.

My rear housing code is QW 06 01 G1.
QW is 3:55 ratio. I know it’s a 3:73 because it had a chrome 12 bolt cover and I put an OEM black one on it. Counted the ring n pinion teeth while I had the cover off.
I’m sure Mike S. would not have bought n installed an incorrect rear for the car.

He wanted you to go a little bit quicker.
