To get the .055" clearance required for the chain it was necessary to clearance the block saddle roughly even with the bearing insert. Could not find any pics of this chain installed on a 3500. Pics of the 3400 installs looks like the block was not clearanced in this area at all...
Surprisingly, the MMS custom pushrods are quite a bit heavier than the stock ones. MMS pushrods weigh in at 44 grams for the long ones and 42 grams for the short ones. The stock pushrods are 39 grams for the long ones and 36 grams for the short ones. This is contrary to the MMS website's claim that they are lighter than stock and will help prevent float at high rpms. Understandably the custom pushrods are slightly longer in order to compensate for the changes made by the custom camshaft so that is going to add some weight however I would expect that the custom pushrods would still be lighter overall than stock to compensate for the extra length required not only because that is what is claimed but especially since this engine will see close to 7000 rpm. Still waiting for the upgraded MMS lifters to verify preload and correct pushrod length
