Hydraulic or Solid roller
Which would you choose and why? Met with the engine builder this week to discuss options. Building a SB 427 using a Dart block. Car will be street driven, goal is 500hp. Do not intend to race.
I am leaning towards the hydraulic for ease of maintenance but I must admit I have no idea what to expect from a solid. The builder is pushing the solid because he says I will have 30+ more hp. I have never listened to a solid but I heard that they sound different. Not sure I know what that means.
Not sure if I will care about more hp since it is an upgrade from a stock 77 L48. It will have a T56 6 speed with 2.66 1st gear and a 3.73 diff.

well I just built a BB 427 for my 69 and went with a solid roller and yes there are power gains.
The only real "maintanence" would be the adjustment of the valves to a set lash.
I checked mine and and it did not move at all, I if you use the good poly locks you should be fine for a long time

If you are building a 427 SB with only 500 HP than a hyd roller will work fine. You will easily get it and not have to rev the motor. If you were going to try for upper 500 HP or 600 with tha tmotor than a solid would be the choice. A 500 HP 427 will run a mild hyd roller. I have a solid roller in mine and yes it does make more noise but who cares. I like the sound
at the power level you want with 427cu you don't have a real need for the solid roller.
