We have been using the hydraulic roller camshafts for some time now. They are a great up-grade from the std hydraulic camshaft, they have no break in problems, no loss lobes later on. They will turn higher than a std hydraulic camshaft and make great power. We have played with several different lobe designs and have some that work better for higher rpm's if needed. We find that these best hydralic rollers will start fallin g of at 6500 to 6600. This also depends on the valve weight, retainer weight and the design of the lobe as well as how much lift it has. We have made over 600HP with the FE strokers that we do with a single 4bl and pump gas. We use a lot of these in the small block strokers we do and have had great success with them there as well. We can get you the camshaft done for 259.00 and the only company that is making a lifter right now is Crane and they are 459.00. If you want to put a lot of miles on your engine and do not want to adjust valves this is a great way to go. Keith
