1996, sure a lot of cams since but I can definitely say there's only been one GMC truck V6 cam that's went through Paul's shop for a performance grind. A lot of people thought this was a crazy idea including Paul's nephew that worked for him at the time. To me it was a childhood dream come true to put a 478 V6 into a pickup truck as well as being a GMC purist
As far as the cam specs I just told Paul I wanted a performance grind cam and he told me just to give him the stock cam as well as the solid lifters that were refaced and he can take care of it. When he did the 478 heads he used longer valve springs from Comp Cams because of the longer lift of the new cam. I will get you the valve spring part number
