what is the most variation in deck clearance cylinder to cylinder you have run? At what point does it create an issue?


'75 Plymouth Duster
Phase I 451 906/590/2-660 10.75/126
Phase II 451 Stage VI/590/1050 9.82/135
Phase III 383 906/Victor-Pump gas 11.30/119

I have seen .017 differences in a set of stock pistons and rods, the rods where the cause I have also seen as much as .006 taper front to rear on one side and .004 the opposite taper on the other side on a stock used production 440 magnum motor that was using one rod and piston at TDC in all four corners using a dial indactor on the piston center at TDC

I have a slight angle front to back on the block at about .003-.004, same on both sides. It looks to move .001 per hole. I have about .008 variation in the rods (a couple have been resized). So by matching rods to cylinders I can vary from .008-.013 in the hole, which puts the quench at .035-.040 with a .027 gasket. I can true up the rods to the shortest length, go .013-.016 in the hole and have quench at .040-.043 with the same .027 gasket. Then again, I can true up the deck and rods, put them .005 in the hole and use a .040 gasket.

I just want to spend where I need to, too many other things that need attention and money.
