This is as much for me to have a record as it is for anyone else. This is info off of the Gen 3 3SGE.

Valve bucket diameter 31mm (Shim under)
1ZZ buckets are also 31mm (Shimless)

Stock rod + cap, nut, stud weights in at ~746g
Eagle 3SGTE rod weighs in at 555g

I'll keep adding info as I work on the thing.
