"The early 360 ('71-'76) blocks are a special case. They use a 4.00" bore (340 was 4.04") but the block was made with the 340 water-jacket core. This means that these blocks can be bored to the same actual bore size as any 340 and have the same borewall thickness. This is NOT true of the newer 360's"
Basically there's enough "meat on the bone" to go to a 4.10" bore.
Cool.
When it takes more than a sweet mullet to prove you rule at the trailer park..
