lots of choice
rods - well i'm split.a lighter piston will help,so will less rpm
those heads/cam will more likely want more rpm so
but then the vert is really too small as well
i have rebuilt rods,arp bolts etc, in my 440 but i shift at 6000 trap 63/6400rpm.i have a SRP piston .i won't aim for over 6500 even when i recam it.
heck as others have said put my motor in a Abody run 10's.
put a smaller cam in it but who am i to say i use a purple 509 cam
