Does anyone know of a reference of '6E' that relates to the LS7?
I a trying to organise approval for this conversion in Japan, and the designation 6E has been specified as an approved engine. I know the 'E' can be referenced to the eighth digit on a VIN, but can't see where the '6' would come from, as I don't think it's just referenced for the C6 Corvette. Google gives me nothing to go on. I don't have an engine to look for a possible casting identification.
Any ideas would be much appreciated.
