Yesterday, me and my buddy went to tune his 14:1 460CI motor and it had a catastrophic rod failure. We had a spark issue at first due to a low voltage condition, with that corrected we began making pulls. Starting at 32° of timing with c16 fuel the motor sounded healthy. After the first 2 runs the engine had ran through the 5 gallons c16 i brought. So we switched to VP110 and bumped the timing up to 35°, at only 6k RPM with 12.1AFR it chucked a rod out of the side of the block. The Aluminum rods were not replaced during the rebuild as they only had 60 runs on them(one did have a small nick in it but it was releived) The rod broke at the thickest part. I posted a few videos on youtube..... looks to be an isolated rod failure?
