My answer to your question will be a “general” answer, because most rods aren’t really rated in horsepower. As a general rule of thumb, most I beam type rods can be run reliably in your typical 450-500 horsepower range. For small block Chevy applications, generally a H beam type rod is good to 750-800 horsepower.

We offer ring set 9154000-030-A as well balancing option 91510202. This balancing option will keep this as the standard external balance rear and internal balance front like all stock 1 piece main engines are. We do not offer the option to internal balance the rear.

Balancers 91015363, 91090010, and 91041262 are all 6" that are good for high RPM use. Personally I prefer the ATI Super Damper 121917781 that is 6.325"
