Rod and Piston weight
Can anyone tell me what the rods and pistons weigh in a roller 305?
I was wondering how far the aftermarket hypereutectic pistons (470-475 grams) are from stock weight.

Depends on the exact year and model but they're in the 465 - 480 range.
The Stock Eliminator replacement pistons are
Flat top
SEALED POWER 3018P
TRW L3028F
VENOLIA 305
TRW L2486
BADGER B417
FEDERAL MOGUL 534NP
FEDERAL MOGUL H534P
JE 143825
CP PISTONS C1-CP
ROSS 99586
Dished
VENOLIA 87-91 305
FEDERAL MOGUL 536NP
ROSS 60671
CP PISTONS C12-CP
Since stock eliminator can't vary much from stock, if you can find the weight from any of these, they should be close.
