Ive had people tell me you can, then other people who know more about building engines talked to Tim @ TBdevelopments he said you cant. plus forged rods have brass bushings for and oil holes in the small ends of the rods, stock rods dont, cause the pin isnt supposed to pivot, you cant have steel pin rotating in a steel rod (stock rods have no bushing). The stock pistons have oil holes in the bottoms inside the crown to lube the pin that pivots in the piston whereas forged pistons have no holes as the pin pivots in the rod, not the piston! if that makes sense haha
