Eagle / rpm rods

There are several technical writings on 6 pack rods vs. Hbeams. Actually the rotating mass of 6pac didnt really help, furthermore the "susposed" strength from 6pac rods over regular rods weren't ever proven factually. They looked nice but that was about it. You can obtain H beams from various mfg's for 400.00 and less. I would suggest the H Beams. To top that off, there are several rod lengths to use. Several like CAT, Herbert ect ect, offer them in 6.76, 6.86, 7.10 for gain on rod ratios. Pistons are also available for the same combos. I've gone 7.250 Billet Crower rods and the rod ratio is wonderful.
