Thanks for any help you can give.
We machine quite a few of the older 327 blocks for splayed center caps as a lot of guys use these blocks for there circle track engines that they use a 3.500 stroke Honda rod journal and 283 mains to reduce bearing friction and weight as those cranks we use weigh 31 pounds after balancing.
And we use caps from http://pro-gram.com/
We have some engines that turn less the 7000 RPM but are making 525 horse as I would worry more about torque and horse power then I would about 7000 RPM.
