I was looking at the SCAT web site and the 6" rod has a pin end dia of 0.927". The stock LS1 rod is 0.943" dia. I don't think that combination will work. All stock LS1 pistons I looked at do not have a 0.927 pin dia. All have 0.942" ins dia. I thought why not use the whole LS1 rod/piston combination. Looking further I found Lunati makes a rod bearing set (PN CR867HP) that will space a 2.10" rod to fit the 2.00" small journal. Also the LS1 rod is 6.098" long and the 4.8 lit LS rod is 6.278" long due to the shorter stroke. If the longer rod is used would it address T Lowes comment about the piston being lower in the block. This is a paper investigation as I have no real hardware to see if this is feasible. I find this approach very interesting. Any thoughts appreciated on this.
The problem with V- engine rods are #1. They are offset and #2. The bottom end is narrower. As far as I can tell the off set is a result of the narrowing of one side of the big end so the V rods can set side by side on a single crank pin. They use the same bearing so I don't know what the "actual" effect would be. I know what some say it would be.
