Piston design and specs information
 

So after figuring out all the equations for rod ratio, strokes, compression height, and numerous other things, I have found numerous combinations of Pistons to work with numerous length rods and crank stroke. Many of these combos use sbc and sbf Pistons mated with various length LS rods. My question is since all these combos work out on paper, can they actually work? Is a 4.030 piston a 4.030 piston no matter what? Many companies use different compression heights on their Pistons, which opens up numerous combinations of Pistons and rod lengths.

I thought using SBC rods was relatively easy and common on the LS, just some honing on the big end I thought. To answer your question, as long as its the right material and design for the us (nitrous, boost, etc.) then it should work fine. The piston doesnt actually touch the wall, just the rings, so it really has no idea what its in.

On the rods, some companies actually advertise rods as being for sbc or ls. I have read about builds using sbc rods in ls engines.

That's exactly what I was thinking on the Pistons! I have found numerous Pistons that are manufactured for ford and sbc engines that would work on stock stroke 3.622 ls engines with using 6.2 and 6.3 length rods. Most of these combinations put the rod ratio between 1.711-1.739, which seems to be the golden area of rod ratios
