They actually recommend i beams for over 9k rpm and h for under 8kI would be very careful chosing these manly I beam rods. The are very hard on the bearing which no amount/kind of oil can protect. Buschur did a tear down on one of their customer who had 16g on their short block. The motor only had 10k miles in it. I don't think he admit it but you can see some wear in cylinder 4 and 3 rod bearings. It probably will be fine with less horsepower and low rpm but if you are going to be shooting for 800hp, I'm not sure if it will be a great choice. Manly does, I believe, makes HD h-beam rods which weight less which can be a great alternative to use. If not there are other lighter I beam rods you can get from other manufacture. Another great thing about lighter rods is that you can rev much faster.
