I ran a set of Ohio Crankshaft H beam rods in my last engine. They lasted just fine until the crankshaft broke, then everything got wasted. Engine tried to throw the 3rd rod journal (# 5 & #6 rods) out of the side of the block, but was unsuccessful because the rod & piston were still attached. Bent bad, but still attached. The biggest issues that I had with their rods was the piston pin bushing was not sized (honed) anywhere near the pin size. AND, I ordered them with the ARP 2000 rod bolts as an upgrade, and it looked like they just swapped out the bolts. The big end was not round unless you backed off the bolt torque to what a ARP 8740 bolt is torqued to, then it was round again. Bottom line, I had to spend more to fix the issues with both ends than I saved from buying a better quality rod. Other than that, were good rods, with no other problems.

Whose crankshaft was that, any idea why it broke? It was the last factory stock forged crankshaft that I will run in a race engine. If anyone thinks that a $700 after market crank is too expensive, just wait til it breaks.$$$$$$, (like 8000 of them), not to mention half of a race season (and I was leading the points when this happened) My point is to the op, the Ohio Crankshaft rods held up well for several seasons with no issues, other than the initial fitment added cost. The failure that I had was in NO WAY due to the rods, it rest solely on the cheap a$$ engine builder (me). Lesson learned. Brian
