Aren't forged pistons available from Wiseco or someone really cheap for these motors? If so, why not add that to the recipe and worry a lot less about breaking ring lands...

I dont think there ring lands are very weak on the new pistons skinnies and his ppl and stock48 are over 850hp on these gen lV's? Seems to be the rods that give out?

If your tune up is spot on you can make good power. I had a 4.8 with a s472 on 22psi and lasted a short time before it needed new pistons. Timing was alittle high for 1 pull at 22psi....didnt crack a ringland but #5 piston was oval shaped lol. If your doing rods you mite as well do pistons.....IMO the rods are stronger (05 and newer) then the pistons

Check out the latest on Denmah's Fairmont. 711 hp on gen 3 junk til the rods bent and 2 broken ringlands. Gen 4 broke ringlands on the dyno. I say push the stock junk to the limits or go ***** out on some shiny forged **** but don't mix the two. Just my . 02

Yeah if you change the bob-weight (weight of rod, piston, rings, pin, locks if any, bearing), ideally you would re-balance.
