Neil,
Thanks for the info. I don't' have my books here at work but I have a 1971
18GK engine with the "middle" of the three connecting rod styles. How do
these compare with the 18V in weight? When I rebuild my engine, should I
change the connecting rods to the 18V style?

No because in HC form the 18V had even higher compression.
9:1. These motors
were pretty over-engineered so they decided to lighten the
internal
components in an attempt to get something back from all the
emissions gear
that was strangling the cars at the time. The early 18V
motors were the most
powerful and most responsive of all the B motors. Just prior
to that, the
1970 cars ran the heaviest rods, emission gear, and the 5
ring pistons. My
GT absolutely won't rev, but I have driven Bs from a year
later that will
rev all the way out to 6000rpm no prob at all. Mine really
does feel like a
tractor motor. <G> One retro step (IMO) was the replacement
of the dual
chain timing chain with the single, but thats about it
really.
Cheers,
Neil
