HP means squat. What counts is reciprocating weight, rpm, and load if you run a power adder. The 7.100 rods are a modern design where unnecessary bulk was removed. Call Tom and ask. He'll give you an honest answer. Mine has Molnar 7.100". The bobweight is 2222. I was told my self imposed 7500 rpm limit was safe. Though it only runs to about 7300.
