How to most people get their pushrods cut? Should I take the pushrods to the same machinest that worked on my engine parts (crank, cylinders, rods,...) or to a regular machine shop?
Also, what tolerance should I give them? +/-0.001"? Below are my numbers for a Raby 9590 cam with 0.426" lift for exhaust and intake. Are these numbers typical? Cylinder.....Intake Lift....Intake Rod Length 1...............0.432................10.567" 2...............0.433................10.607 3...............0.431................10.640 (required 0.03 shim) 4...............0.424................10.578 Cylinder.....Exhaust Lift....Exhaust Rod Length 1...............0.410...............10.623" 2...............0.409...............10.618 3...............0.412...............10.663 (required 0.03 shim) 4...............0.410...............10.612 |
