Question 7.3 IDI Piston Weight Variance

Hi guys, long time no see.

I'm rebuilding my 7.3 that I rebuilt back in 2017. Had a piston go to s***. I bought a new piston but it's 19grams less than the other seven. What is the spec on allowable piston weight variance for the 7.3 IDI?

Yikes. 19g is pretty awful. Unfortunately I didn't weigh mine before installing them. Historically, 1 gram is the target for pistons.

You got a spare standard size piston on hand? I'm not too far from you.
