'78 Avanti ll Number

[mfg]

The engine serial number on a 1978 Avanti ll is located to the left of the distributor, on a machined pad....True?

[Avanti83]

False, Numbers on my 74 and 83 were where Chevrolet put them on the front of the passenger side head. Not sure which left you are describing but that would put it on the intake manifold in either case.

False is correct....but are you sure the engine's serial # is on the front of the passenger side cylinder head?

I can't speak to the 78 but my 83 has a number stamped on the pad and I used the one on the 74 to determine what the engine was.
