I-Beam or H-Beam

I thought the breakages were isolated and due to material problems more than design. The ones I read about were under the supposed 500hp/7000 rpm limit.

I figured when I started this project that stock rods would be OK; the Eagle rods are (supposed to be) stronger and they are lighter than stock. And I would have to buy stock rods and have them reconditioned if I went that route.

The H-beams are quite a bit more expensive. I don't have any problem paying for them if I need to; just don't see any sense in buying the more expensive part if the I-beams will do just as well.

Thanks
