After doing some research for a friends engine build, I found that there are often issues with retro-fitting hydraulic rollers to older, non-roller blocks. Some issues are, limited revs because of the heavier lifters, noisey valvetrain, etc. It seems to me, that for a street driven old musclecar, that a solid roller just seems to make more sense. I have been running solid FT and rollers for years and really only run the valves twice a year and even then, there are rarely any issues there. The intent is not to start an argument, it just seems that for older motors, there is less drama to a solid. What are the advantages of a hydraulic roller in these circumstances, other than not having valve adjustments, that I am not seeing?
