Does anyone know who I can contact to help identify the following numbers:
The vertical stamping on the front side of the engine block, passenger side of center (by dipstick), on a 68 302 block? The stamping is 2075.
Also; is it correct to have an outside casting # of 41 on the passenger side head and # 40 on the drivers side head?
The only stamping that I am aware of on the front of the block is the one on the small machined pad that sticks out on the driver's side below the distributor. Your 40 and 41 probably indicate which particular mold the heads came from.
