Molnar has them in four flavors. 8/6 bolt and 2.2/2.375 pin. I'd highly recommend the 2.200 pin if you're buying rods at the same time. No good reason to use the extra heavy Mopar rods. I also don't think there is any reason to use an 8 bolt flange at 750 hp but sometimes you have to do what you have to do.
