Just wondering if there's a preference between LB7 or LLY pistons to have delipped? Now before everyone starts telling me they're the same hear me out...
I've got a set of LB7 and LLY in front of me and there is a slight difference in the lower oil ring land and wondered if it effected the strength or ring lubrication...
First pair of pictures are LB7
As you can see they have a pair of holes fairly close together that go right through the oil ring land to the inside of the piston. There is another pair of holes 180* and these are perpendicular to the wrist pin.
These are the LLY pistons.
As you can see these have what I would call pockets. These don't go all the way through like the LB7 piston. They are also located further apart and are parallel with the wrist pin, one on each side.
Now my question is will one piston or the other get more oil, fresher oil, cooler oil or anything to the rings or cylinder walls or anything faster? More efficiently? Is one piston stronger than the other? Is one more prone to a hot spot?
