Unless you are going into racing, or planning on hauling a very heavy
trailer, save your money and forget about it.
Even in racing, All 327s including the 6500 redline fuelies were 2-bolt main
engines. The '67 Z-28 302 was a 2 bolt.
Most passenger car 350s are 2 bolt mains and they haul a reasonable trailer
load also.
Cost is the price of the caps, price of align boring the caps, and
drilling/tapping the block for the extra bolts.
Look around on eBay, you'll find plenty already don't and at a much cheaper
price.
