ROD TO CAM CLEARANCE GAUGE
Using a plastic banding strap as a feeler gauge works great to check for clearance. The straps are generally .035-.045” thick, so you might want to double them up to check for the minimal .050-.060” clearance recommended. They work great as they easily bend to any curvature you need. If you can’t find these straps around, you can always cut any discarded plastic jug or bucket into strips to use. Tip: I have found that on Chevy V8’s, rods # 2, 5 and 6 are the ones that get closest to the cam lobes.
