Confusing to me is the 3.59 number... either it's 3.58 (Mopar 360 but not a stroker), or it's 3.79 which in fact would be a stroker crank.
There are cranks for both strokes available... what rod length to use depends solely on the compression height of your pistons.
Btw. funny strategy to buy pistons first and then worry about crank and rods? :poke:
If Bigboy 68 is Rodney (memory?) he has more mopar stuff than you and me combined. And my garage is full, with the yard overflowing. It’s more about the deal, unique builds for him. He has been known to make full size wagons go fast.
