This what I run. 15-1 572, ported -1. Comp; RX 1718 int lobe (285@.471"). XCX 1862 exh lobe (292@.471") ground on 112 LCA (gross lift .799"). Uses PAC 1224 spring @1.950. T&D paired rockers 1.7 ratio. We checked the last set of springs at 200 passes. No pressure loss, same as the new set. With 440-25 Indy cross ram and 2 Eddy 750's the car will run 9.1-9.2 145-146 in any weather at 3340lbs. Best of 9.00@150. Lash stays consistent.
