The rods are Carillo 6.500" H-beams; these are more Busch/ASA circle
track parts. The 6.500" length makes a turbo dished piston a tight fit
but they're the most common quality rod available and like Smokey Yunick
says, "Use the longest rod that will fit...."
In this picture they are just returned from the balance guy (Johnny B. who merits a whole page by himself!) and the shiny spots on them are from the weight matching. The SPS-Carr bolts in them are about the best available, I'm told. They've been re-sized and re-bushed as well; the small ends take a .927" SBC style pin, which allows more (and cheaper) pin choice.
