If I was doing this combo I would use a Molnar crank and rods up to 900hp and 7500-7800rpm. Tom has put a LOT of R&D and analysis into his products. If you are wanting to make more power or turn more RPM I would use aluminum rods. They are WAY easier on everything else. R&R, BME or GRP are good choices. They will last 300 passes as long as they are heat soaked before the first pass and you don't motor down on them. All the OLD myths about aluminum rods are just that. MYTHS.
