Finally, we tried a custom B3 T&D setup using shorter 1.45"-fulcrum 1.60 rockers set up for .650" net lift. The pushrod geometry and sweep pattern were basically "nuts on" w/ Jim Miller's Mid-Lift rocker arm geometry design, but the actual lift curve wasn't significantly different than the Hughes 1.60 setup w/o the B3 relocation kit, so I kept what I had as what I was hoping for was a net increase in lift to go along w' the improved geometry.
