Re: Confusion on 351W Rods for 393W

You need a custom made piston. It is possible to hone the Speed pro pistons to match the rods but there are no lock grooves in the pistons and the rods have bushings so they can't be pressed. I don't see a way out other than a special piston to match the rod or use stock 351W rods like Ford did.

Experimental Ford parts collector.
