Harland Sharp rockers for my setup? Hey everyone. I'm putting my setup together piece by piece, and am trying to figure what else I need. Basically, I have a G5X3 on a 110, full intake, full exhaust, ported throttle body, short belt (!power steering), will be getting heads soon. and I want to get an underdrive pulley, maybe an electric waterpump, and I was thinking about picking up some Harland Sharp 1.7 rockers too. I don't want to build a total dyno queen, but I'd like to get as much horsepower as I can out of an H/C setup and have a smooth running car. I like the results I've seen with these rockers, as well as the price. I need input and opinions on them. Do you think I could benefit from these with my setup?

I am running the HS 1.8's. I "thought" I felt a bit more power at the top end but I'm not sure. I did have an issue with pushrod clearance with the heads - very light interference. Gunner at Patriot ground the holes a little bigger for me. My setup has a noisy valvetrain with one lifter system in particular that stands out. I think may have been there before the rockers though.
For the most part the rockers have not been an issue. I used a 7.350" pushrod. I used an adjustable to determine the length on #1 cylinder then sent it off to Smith Bros. They used 0.045" for the preload.
My problem is oil consumption.

I ordered a custom cam, and with the specs I chose, 1.7's are my only option. I have heard of 8-10rwhp increases with these, and plus, I would rest a but more assured with brand new HS rockers than old stockers with .615" lift.
