I`ve got both ... obviously not on one car . My ERA has hydraulic rollers and according to the dyno sheet makes 620 ft/lbs at 4100 rpm and 612 hp at 5800 rpm ... and the torque curve is almost flat . Robert said it can go 6300 to 6400 rpm ... but why , as max power is at 5800 ?? There are certainly guys out there making a bunch more hp and torque , but I`m happy , and so far my valve adjustment will be limited to once a year if then . My 427 solid lifter Galaxie is another story , as I go through those valves in the spring and winter when I put it away .... and there are always several that are off by about 3 thou .
Which is better ??? Depends on you and what you want/like to do . If you love adjusting valves and the sound a solid lifter engine makes , go with solid lifters ... if you want to make good power and have minimum maintenance , go with hydraulic rollers ... jmho .
