Procomp electronic connecting rods ?

U can use a .020 over 440 piston with the 5.35 rod if staying stock stroke. A .060 440 piston will be .040 400 size. Pick ur compression ratio from there. KIm
Oh yeah for my 471 I'm running 6.70 with a 1.320 ch piston, 4.375 bore.
For my other future offset 3.375 stroke to 3.50 I'll need a 1.53 compression height.
But it's only because I wanna use the rods but I don't know if I trust them in a 600 hp engine
