mfg Posted August 5, 2014 Report Share Posted August 5, 2014 The engine serial number on a 1978 Avanti ll is located to the left of the distributor, on a machined pad....True? Link to comment Share on other sites More sharing options...
Avanti83 Posted August 5, 2014 Report Share Posted August 5, 2014 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. Link to comment Share on other sites More sharing options...

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. Link to comment Share on other sites More sharing options...
