Title: Piston weight
Post by: scott foxwell on July 21, 2017, 06:43:17 PM

Does anyone know the approx. weight of a stock cast flat top replacement 390 piston, +.030" with (4) valve reliefs? No idea what brand it is. Have my engine apart and thinking about replacing them with an Icon IC682 and wondering if I'd have to re-balance. The Icons are 533g (piston only) according to the catalog.
TIA

OE was heavy.  You would need to balance.
