Yes, definitely, but it isn't enough to go looking for unless you are racing 
in a stock class. In improved, the added compression and heightened RPM range 
may militate a 5 main cross-drilled crank.

But running a blue-printed and balanced 3 main against a similarly prepared 5 
main - the 3 main has a slight power edge, and also 'feels' more 'revable'.

Bill (who raced for some years in just such a class - blueprint, balance, and 
race 'em)
