Thats what I ment

the firing order is 1 - 2 - 7 - 8 - 4 - 5 - 6 - 3 so
1278
4563
3 and 8 are companion cylinders unless my thinking is too inline six
Yes, the 12734568 firing order is possible. I meant the 15426378 firing order can't be done without a different crank.

You can't do that without a different crank.
What were the results of runing the modified firing order? smoother runner? more power, less power?
We have not broke one crankshaft with the alter fire pattern. Obviously I cant say who is all running them but they are in some of the top 3.0 trucks in the country and a few 2.6 as well. Knock on wood. Smoother harmonics, from relieved cylinder pressure. Power gains are minimal when comparing cam grind to cam grind.
What year model is your LMM? I know waranty isnt what it use to be but back in the day if the term wasnt up they would work with you on the miles. In other words 3 year 36k mile waranty the dealer could arthorise a repair on a truck with 40k on it if the 3 years wasnt up.
any more details? what HP are you running? has it gone over in oil changes? towed heavy and hot? anything funny with the oil PSI before it went? Anything unusual in driving habits or engine behavior?
