I have not seen a kit advertised for a very long time. What exactly was a 317 stroker? 5.4" rod, stock crank and what pistons? Or am I remembering incorrectly?
302 block 3.100-inch stroke Not a stock crankshaft.
High-nodular-iron early 302 crankshaft
Eagle 5.400-inch connecting rods
Ross ultralite forged pistons
Clevite 77 main and rod bearings
Childs & Albert piston rings
Kit price: Starting at less than $1,800
You would use a 1.25" CH piston.
An offset grind requires different connecting rod ends/bearings, because it decreases the diameter of the crankshaft, and it could be a possibility.
