Need 318 help/advice
Hey Claude C, are you confused yet?
A bunch of parrots and actuall folks testimonials, both pro and con...
Let's analyze this some and break it down to groups.
1.Those who have run them on the street.
2.Those who just parrot what they've heard or been sold.
3.Those who have modified and run them and made great power with time slips to prove it.
4.Those who have flow tested them and other heads for comparison and have modified and verified the improvements at track on a flow bench or on a dyno.
The only meaningful opinions are from 3. & 4.
Not out of disrespect,l to 2 and 1

People want "x" amount and don't realize that "w" ..was plenty, for them.
