D4B DC mods like the LD340 DC mods?


And these.
I (well, actually my machinist) ordered 3 sets of made in the USA, Forged custom 273 pistons from Race Tek a few weeks ago. They should be ready in a few weeks, and were $700 a set. I got 2 sets for me and one for @66fs.
Would love to learn more about these.
