Update; spoke with Mike at MrHotRod 6 and he recommended getting some stronger rods for the heavy TRW forged pistons if I wanted to go much above 5000rpm. Unfortunately most aftermarket 250 rods these days are configured in the 6" size versus the standard 5.7" size. As luck would have it, Eagle is spinning up production on these again so I got a set ordered for the build. Now I can be confident that if/when I add forced induction my rotating assembly will be stout enough for the added pressure and rpm! Thanks to Ray from Eagle and Mike/MrHotRod6!
