Nice! Looks cool. I wish you would have pushed the engine on the dyno just a bit more to see where it made peak HP and where it would have nosed over in power.

Who's Hyd. Roller lifters we're employed?
Stock 5.9 replacement Melling jb-2225 lifters were used. Our hp gains were so low per hundred rpm at that point we did not see point of pushing further. I suspect peak would have been 5800rpm.
