I have a small block 400 chev,just put new flat tappet comp cam and lifters in it idles sweet as but starts ticking under revs and ideas? This condition shows up as a knocking or metallic pinging sound andis most commonly attributed to improper ignition timing, lean air/fuel ratio, or improper fuel octane level. Gudgeon Pin (Piston Pin) : Method, Design & Working Conditions :-, 1. Reduced demand for gudgeon pin in several applications sectors has hampered market growth in 2020, resulting in a drop in overall growth over the previous eight years. The piston pin is also used to connect the piston and connecting rods within the internal combustion engine, where the piston pin transfers gas pressure into the connecting rods. BITZER Piston pin.
