Hey guys I sent my new 49-410-8 cam back to Comp cams and after talking to a nice gentleman there I now have a custom ground 4.0 cam thats suppose to make at least 18 hp more then there big cam the 49-422-8!!! I can't wait to get it going. I also have the Comp cams dual springs and Crane cams retainers to go along with my 98 style heads. I'm just waiting to get the retainers in from Summit to take to my machine shop and have them all installed. I've done quite a bit to my truck since the sites been down so I'll have some pics up soon. Fill me in on some news form the other supercharged gang?? Later Doug904.
