Another issue with these 4.25" stroke crank short blocks (482, 484 , 496 etc..) is their heavy rotating assemblies. The eagle rods uses (H-beam) is v-e-r-y heavy. This, along with valve train limitations, limits the usable RPMs of our stroked FEs. You guys, Ernie included, that have a stock stroke 427 will always have a more "rev-happy" engine. Those of us that are stoked on stroked are willing to give up statespherical rpm limits for mountains of low/mid range torque. This minimizes the need for any solid lifter on these large strokers, flat tappet or roller. Also, in a lot of cases with stroked FEs we will have run out of intake and carb by 7K rpms (dual plane intake w/ 750/850 carb and other "streetable" combinations). There's quite a few things that'll limit RPM other that cam design.
