Finally had some time and space freed up at the same time in the shop this weekend. Through the 3200 spring and whoa, huge difference!! With nothing else done , beside some very inaccurate thread counting when putting the power screw in(turned in a bit more), we took it out and made close or right at 70psi of manifold pressure. It was dark and the truck was getting pretty loose so wasn't really looking at the gauges but EGTs weren't higher then 1200-1300* but I never saw what the primary was doing. Lift pump is certain now, as it really begins to lay down up top.
Next question. Does it take forever to get those pumps to bleed the air out of them? It had died on is about four times. We stop, bleed the lines, and it fires. It only seemed to do it after a hard run. Ill get it back out this weekend when I get home and see what it does, if I can keep the boots on it.
