Good news and bad news. My Icon pistons cam in. I dropped them off at the machine shop this morning and unfortunately just got a call from them. He weighed the original Magnum 5.9 STD bore pistons, rings, and pins and then weighed the Icon piston assemblies with the lightened pins and the lighter ring set was still 50 grams heavier than the originals. So now I’m looking at balancing the rotating assembly. Just sucks because I haven’t ordered my flywheel yet. Which means I’m delayed yet again at assembling this engine. I’m going to order the flywheel from American Powertrain I guess. Can anyone chime in on if this is correct. 130T, 10.5” clutch or do I need the 143T flywheel? I’ll be running the original bellhousing from the 340 that came with the car as well as the original 833 4-sped.
I need to get the flywheel ordered so I can get it and bring it with the balancer to the machine shop so he can balance the rotating assembly.
