there might be a set out there.... I had a tough time finding a set 13 years ago........

You do have options.
1) get a custom made piston - Traum can make you a set for about $700
2) you could use Molnar Technologies "smaller" rod (40/20) - about $440 a set, and then use a set of smallport pistons....

OR, you can just use a 42mm crank and rods with high comp pistons.

I am assuming you have the early big port engine. The big port 4AGE came with both the 40mm and 42mm cranks and rods. If you have the 42mm crank the you just need high comp pistons.
