You can buy after market splayed 4 bolt caps. You need to have a competent machine shop install them. A 2 bolt main with studs is stronger than a 4 bolt main with bolts. Don't waste your money unless you plan on spinning it to 7000 rpm regularly.

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.
