318 Pistons: baffled

Marcohotrod said
would you swap for the heavier later pressed rods, cuz the 1964-71 1618699 lighter 273-318 rods only came floating. and I do not have any L2329f+20 pistons, but summit is not the only piston source in the world

I sure would. In a flat second. Because it opens up more choices for pistons.
