273 Rods work in a 360?

yes, but 273 rod has a bushing in it, 360 uses a pressed pin. piston needs lock ring grooves cut in pin bores, unless you're using after market, pistons, some come with lock grooves. just food for thought
Thanks. Yes I am using aftermarket pistons. Enginetech pistons P1530. I know cheap! But I've heard some pretty good reviews on Enginetech.
