First, Thanks GP, DJ all on the port stuff. I've had it with hydr lifters. I have had rockers swivel, I have bent pushrods. I had a tapping, I could push down on the pushrod side of the rocker and mash is 1/2 inch into the lifter. I tightend the rocker more and I could tell it was further down than the others , It was ok, for a while. Then it pumped up and kept the valve from closing. I turned around and came home. Next day, not so bad. But I ain't driving it. I'm building a new motor and using solid roller cam. I had one in my sbc race car, and it was perfect. What should I expect on the street? Are there any disadvantages?
