New 5.7 harland sharp rockers

Steve- The rockers retail for 1800.00. I took the risk of being a "guinea pig" and agreed to give them educated feedback so I paid dealer cost on them. These thing are a work of art, and they put in countless hours of R+D to get these things to bolt on the stock head and clear all of the valvetrain an valve covers with no modifications. The only other option for an adjustable set up is from Jesel at a price of 4500.00 + machining to the heads. These are a work of art also, and open up alot more valve spring options. However, once you machine the heads, they can only be used with their rocker set-up. Comp Cams grinds solid rollers for these motors. My cam has .696 lift on the intake and 285 degrees of duration at .050 . The engine really starts making power around 6500 rpm. I need to shift this thing at 8000+ rpm and my valve spring aren't safe above that point--thats why I'll be changing to a stronger spring. The engine is in my 67 Cuda Fastback and I'll be running SuperStock with it once I get all the bugs worked out. I need to loosen the converter up ALOT, and play with the ignition setup.

5.7 Hemi- If you run a solid roller, you pretty much have to run an adjustable rocker. It would have been cheaper and easier for me to run the hydraulic roller set-up, but I wanted to try to do something different and push the limits. The Drag Pak cars are making tremendous power with the Hyd roller and stock rockers, but like I said I wanted to be different. I decided to throw a carb on it and stick a solid roller in it. These engines have the potential to make HUGE power with a small displacement but NOTHING is cheap when you build an engine for high RPM.
