A camshaft swap changes more than lift and duration. Learn why LS/LT pushrod length, hydraulic-lifter preload and rocker geometry must be measured with the actual parts before startup.
A camshaft’s advertised maximum lift does not prove the valvetrain fits. This guide explains installed height, seat and open pressure, spring rate, coil-bind clearance and retainer-to-seal clearance, with a real BTR spring example.
Stage 1, 2, 3 and 4 cam labels are not standardized. Learn how duration, lift, LSA, overlap, converter, compression and valvetrain requirements determine the right camshaft for your build.
