[QUOTE="tbsimmons, post: 1227850, member: 2026"] I have an opinion like everyone on valve springs. If you had solids I was going I mention to you the same thing I did to Eric when his truck took a crap. You don't have enough seat pressure or ramp speed on the cam to warrant solid lifters. I think the valve springs are too strong for the cams ramp rate in these truck. You have more spring rate than I do in a fast ramp cam spinning to 7000 in a small block. I know you have back pressure to take into account but I don't think it's high enough to have a high seat pressure. But it also could be the lash of the lifters being a little off since we really only have push rod length to adjust preload on the lifters without machine work. Sent from the bat phone near a drilling rig. [/QUOTE]
