273 Commando Slugs

65 Val,

"Of course, with a new build instead of modifying an existing 10.5 "S" motor, you could just mount the pistons on the rods to keep the rod numbers correct, left bank and right banks reversed, notch to the rear."

"towards fender and turn the slug and rod 180"

Ok, you are forgetting that I said turn (rotate) the piston and rod assembly 180, so that the notch at the front of the piston (meaning that the notch should point towards the front of the block), is now pointing to the REAR of the block, on the opposite bank. Piston and rod assemblies 1, 3, 5 and 7 are now in holes 2, 4, 6 and 8, installed backwards. The piston will not hit the head, the pee hole in the rod is still facing the cam, and the offset is reversed. For both banks.

The pop-up is towards the outside of the block, regardless of which bank it is in, to match the combustion chamber of the head. When taking #1 piston and rod assembly, turning (rotating)(reversing notch from front to rear) it 180, and putting it in #2 hole, the pop-up is STILL towards the outside of the block to match the combustion chamber of the head, and of course the rod will still oil the cam, and the offset is now opposite of factory.
