atkinson40 Posted July 30, 2009 Report Share Posted July 30, 2009 I'm trying to determine the piston size in my '72 PU. On the block it's stamped as a L18 so I know it's had an engine swap from the original L16. I took the piston to the local service station and he measured it at 3.304". I looked in the manual and the only piston coming close to that size is listed as a L16 with a .0394 oversize. Did we measure it wrong? Thanks kevin:confused: Quote Link to comment
