Todays technology and ramp designs are nothing like what was available ten to fifteen years ago, I have a solid roller Ultra Dyne, Bullitt cam in my new bracket motor with Jesel paired shaft rocker system, once the motor starts to spin over I can NOT feel the valve springs(325 Lbs. on the seats and 840 Lbs opend at .780 lift) working at all
I'm waiting to see if I dyno this rascal first or put it in the bracket car to see what it does at the track
