The map rods have grooves cut away at the side of the rods instead of the holes.
Thanks Allan. It looks like both the MAP rods have 'notches' cut into them at the TDC point.
and the 'blurb' goes on to say :
"Innovative machined piston oil squirting notches"
"Unlike the stock BSA rods, these rods have been designed without a big end oiling hole because it is not necessary. Other oiling systems take place of the hole in the big end."
Did the steel capped rods used in the A70 have the oil holes drilled?
