Mixed ratio roller rockers?

Arco, Have you been smoking the drapes?:lol:
Bleed down lifters change the rocker arm ratio? Is your set magic? Mine don't. They bleed down at low rpm effectively reducing the duration the engine sees for more vacuum, but they don't change effective valve lift. Especially not at anything above low idle.
He's thinking of putting a 1.6 rocker on effectively increasing lift and/or duration, the exact opposite effect of Rhoads and other bleed down lifters. He's looking to make more torque across the entire RPM range.. If I'm wrong, please correct me, Orange dart.



Orange Dart, mixing rocker ratios is a fairly common thing.. make sure to check piston to valve clearances at max lift so there is no interference... if you have a competent machinist/builder who knows how to do his work it shouldn't be a problem.
Some of the experts will chime in soon I'm sure.
