Amici:
My first inclination is that all this talk about a cross flow head for the
TRIUMPH TR engine has been generated by our close proximity to APRIL FOOLS
DAY.
A cross flow head would provide opportunities to make things less
complicated, and thoughts of getting that exhaust header on the other side of
the block and away from the carbs is certainly a turn on.
As with every racing upgrade, you tend to expose the next weakest link, and
history tells us...it did not happen. Why not? Problems? Was the next weak
point the block?
Love to hear some input from people with hands on experience.
