The crank that JR makes for the Patriot block has a stronger 1.1" rod journal.
JR has rods and pistons for the Patriot block.
The wrist pin is also larger (.625") and stronger than the wimpy .490" wrist pin.
Both make sense to me.
However, if you want to go with a really big piston, good luck.
If you want to use a big Wiseco piston (say 3.1") you go back to the .490" wrist pin. Yes you can use the ARC or JR rod for with the .490" wrist pin but then you must use the ARC crank with a 1" rod journal.
There goes the advantage of the bigger rod journal and wrist pin.
If you want to use the stronger 1.1" rod journal and the .625" wrist pin then you will have to have some pistons made if you want to use a really big piston. JR doesn't make 3" or larger pistons with the .625" wrist pin.
