RE: Crank questions

Greg,
I run mine to 6200. It's a super strong cast crank, like all FE cast cranks. I know people who spin them to 9000 but they have more money than I do. Usually something else will break long before an FE cast iron crank.

You should be careful about using good engine assembly techniques and parts throughout the entire motor. Plenty of valve to piston clearance, good quality forged pistons, the lightest, strongest rods you can afford with the best rod bolts (ARP). Use high quality one piece valves, valve springs that match your intended cam, etc. Screw up on any one detail and it wipes out the rest.

The IU crank should be the least of your worries. Just have it magged and balance everything before final assembly.
