I run a TR4 - tractor engine and all. To the best of my knowledge, it is
totally 1060's legal -- all stock internal parts, identifiable as such
per the 60's rules, no roller rockers, etc.
This limits me to 6000 rpm or the crank or rods go BANG!
Competitors in my class with more sense run billet cranks and Carillo
rods (absolutely illegal in the 1960's). Do I care? Heck no, especially
on the occasions when I run faster than they do.
Would I follow their lead in parts replacement? YOU BET! primarily
because I don't think that fellow competitors or spectators really
desire me to run an engine that is explosion -prone. They and I enjoy
the racing and the spectacle.
Will I get a performance advantage when I too install the better parts?
SURE - because then I will be confident enough to run the 1000 rpm
higher like my fellow competitors. Let's face it, this is what my
Professor of Philosophy 101 called a historical dichotomy, I think. Kind
of an unsolveable problem.
