Here we have a nice clean complete 5 piece set of original 1970 Boss 302 4 bolt main caps stamped DOZE 6015 B. The Boss 302 was a hard charging motor which demanded extra support for the crankshaft and that was why Ford added the extra thick Hipo style caps with an extra set of bolts to help with the abuse. All Boss 302's came with the 4 Bolt main Block that's where the main caps came from. A valuable piece for a builder due to its completeness part number it is a plus for a restorer who is on a budget. This auction offers a set of caps which have been inspected and are found to be in ready to use. We see No signs of damage or repairs so they are sure to please the new owner. This pieces were part of a recent buy out and are what I would refer to as extras and were purchased to get some other items.Please look in our other auctions for the items such as a A rebuilt carb, a 10:10 70 Boss crankshaft, 69 Boss 302 balancer and a pair of valve covers which are all in our other auctions.Not so much a find for the buyer who is restoring their Boss Mustang as this would help a racer build an awesome boss motor.
