This discussion leads me to a question:
I have a 70 MGB, car # 208609 with engine number 18GH-RWE-H33177. I just
finished tearing down the engine in preparation of having some machining
done.
I noticed that the rods in this engine are of the 5-main angled split
type which were used in the GB-GF engines. According to Moss & VB this
engine should have the horizontal split type. I have some history of the
car, but nothing to indicate that the engine was changed. Is it possible
that MG still had the old rods/engines around in 1970 or am I looking at
a pre-70 engine?
