My brother and I just got finished installing his new DD cam and Donnelly ported head. He saw roughly 400 deg drop in egt and about 8psi loss in boost. He didn't think the truck was much stronger (however we didn't anticipate it to be much stronger), but egt's were way down. We didn't have much time to test because he was in a hurry to get back to Las Vegas, however I'm curious to see how he likes it over the next few weeks. I'll be able to give some more solid numbers in the next few days.
