what rods would be better for my build

Keith Black pistons can be used in either pressed or floating applications. In pressed pin applications you don't use the spirol locks that are provided.

The Eagle SIR rod is a screaming deal for a 500HP or less application. I got them from Mancini for $219 for the set. They are stronger than a 340/360 rod, weight less, come with top shelf ARP cap screws and are bushed for floating pins.

The machine shop that did my machine work checked them out and the machining was dead nuts and they were all within a gram of each other weight wise. The owner said that he uses those rods in a lot engines he builds and is always amazed at the quality of the rod for the money.

My observation is strickly visual but the forging is much more consistant and has a much finer finish than a stock rod and the quality of the machining makes the stock rods look pretty bad.

FWIW, The machine shop also comment on Keith Black pistons. The consistency of the weight and dimensions of their pistons are far superior to a lot of the high end forged pistons they use in their race engines.
