408 budget stroker ?

Google 360 Mopar Stroker pistons and take your pick. Consider the hypertectic (dp?) by KB Pistons.

OE rods will require grinding of the block. If you're having OE rods redone and since you're balancing anyway, get some SCAT I beams. Lighter, stronger and no grinding needed.
This ,on rods... KB'pistons,are nice.. an extra couple bucks,gets you Icon forged.. Those KB 356 pistons ,are a waste ,with a closed chamber .. The pedestal is "mill till needed" ..,actually outdated technology, in piston abilities now.. .
