Old - Hydraulic ft: 240/246@.050, .507/.510, 110lsa
New - Solid ft - 248/252@.050, .538/.544, 110lsa
So, not a ton different, but should make more power and take better advantage of the TF 240's.
Factoring in lash, they look almost identical. I too would always lean toward a soild.
yeah, I like solids too. After having to replace 2 hydraulic rollers in my last engine, and never having an issue w 3 previous engines that had solid FT's, I decided to go w the solid. Also a change from my previous self, I asked for the size smaller than the original cam recommendation. Formerly, would have asked for the next size up . I've definitely gone soft.
