[QUOTE="me2, post: 353014, member: 3825"] Please tell me how to do that ! I forgot to post above that the flex plate balance is still one of the things I am trying to figure out. The Ford flex plate is keyed to the Ford crankshaft and it has big balance weights hanging on it. People tell me the 6.7 is probably externally balanced by the flexplate. Dodge/Cummins flex plates are NOT keyed to the crank but do have balance holes drilled in them. What is up with that ? Are they just balanced unto themselves or is something else going on ? I spoke with an engine builder this morning that told me a) they could balance the flex plate by itself and b) it should really be done together with the crank, rods and pistons ! But the same guy told me that I should replace my 6.7 crankshaft with a 5.9 crankshaft because the 5.9 cranks are stronger. He didn't realize that the 6.7 has a longer stroke. So I don't know what to believe. One more thing. I'll be making up 2 flex plate/adapter assemblies and carrying one along on the truck at all times so that if I break one on a long trip, I have a spare ready to swap in to get me home. Nothing worse than having a custom made part fail and not having a backup available. FYI, a Ford 6.7 flex plate is about $80 IIRC. One more little tidbit. A little birdie (not Mark K) told me that it would not be possible to weld the Ford flex plate without it cracking down the road, more so than a "normal" flex plate would, due to the heat treatment and metalurgy it has. Whereas some other flex plates can be welded, the 6R140 flex plate should not be. I know that the starter ring gear is welded to the 6R140 FP as are the balance weights. That is different from welding in a new center, for example. I've got a ton of other things to blather about from stuff I learned recently, but I want to focus on my swap right now. [/QUOTE]
