I notice the same lopsidedness in pistons 1 and 6, not in piston 2. I haven't checked the others.

I hear a set of custom rods is not a cheap alternative to dealer rods at ~$200 each list. Then there's pistons and sleeves and whatnot depending on how they measure when the engine comes apart. $4800 for a short block from Metric Motors starts to sound like a bargain. I'm working on getting more solid quotes on what a set of custom pistons and rods will cost.

I'm not sure I can drop the pan without lifting the engine. Now that the head is off it's not a lot more work to yank the block. Fortunately I have the 3.0 block to keep the car on the road so I can take my time deciding what to do with the 3.5.
