Built a 454 using original truck connecting rods. Used ARP rod bolts #135-6002 and did the torque down on the bolts 3 times as instructed. Later, after the engine was installed in the car i became aware of the fact that the machinist did not chamfer the holes in the connecting rods before pressing the bolts into the rods. Engine has been running great for several rod runs with some heavy duty use, about 500 H.P. and turning upwards of 5500 r.p.m. Just wondering if the rods had enough chamfer or any at all, or if I need to concerned with this at all. So far, the engine has performed great. New to the site but look forward to much engine talk. So hello and thanks for any insight into my question.
