6V92 Red Block

[Don Bradner]

It is hard to be positive on anything in terms of engine history, but I don't
think any 6V used in a BlueBird ever had electronic controls.

I think even the first 8V92s used in 1986 were mechanical, and it may not have
been until 1988 that DDEC I was applied to them. Probably only a year or so of
DDEC I before DDEC II became standard.
