Wondering the same, even for extreme high rpm applications and deceleration, such as autocross, on gen 1 type rods, specifically your standard forged I beam.

John, ever done this mod to domestic V8 stuff? So i guess you would only weaken the rod wherein it would fail on decell, such as when rod bolts fail? Keep em comin. -scott

@scotts439 - I haven't had any rods fail in this area. The LS-7's have similar weight reduction on the Ti rods, only more drastic. Diesels have been using this design for over 5 years, the automotive guys are finally getting it.

How do you replace the small end bushes on a trapezoidal shaped rod? Thx.

@jrgm3 - I have special fixtures for doing some of the rods, others I replace with a cylinnderical bushing, fit the pis, and then shave the sides as needed. Getting them out is the fun part.
