Ford 5.0 HR-258d-SBF 206/212 512/520 Hydraulic Roller Camshaft Mustang 302 351

  

Want a cheap thrills cam for those budget builds or daily drivers? Have many years of experience and understand that every part has its place? Then these are the cams for you. If you are building a high dollar build or applying a power adder, or you feel you are the second coming of Smokey. Or Dyno Don you need to find another source for your project.

OEM cores that are being reground and may have some imperfections but will be functional. I choose to sell these for those that want a budget way to get into the hydraulic roller scene but don't want to spend a few hundred dollars doing so. Since these are stock OEM used cores, I have no timing actions and they come with no cam card. The only specs I can give you are what is listed down below. Again, these are for budget builds or daily drivers.

Not for projects were 25 pounds of boost is involved. Now you can build a beater and mud run the h. You can also slam together a banger for a 150 shot. I've had a guy win a drag series with one and many returning customers. I've also had buyers expect Way too much for something they should have never bought! The turnaround time on these cams are about 4 days. You might want to keep that in mind when making your decision. I will try and do my best to get you your order as soon as possible because I have been in your position: wither the item is for a customers' build or for gathering parts for a future. Just do me a solid and make a decision as soon as possible, Thanks! This is a Hydraulic Roller Camshaft for a 302 or 351 roller block originally equipt with a hydraulic roller camshaft. This is a regrind that was ground here locally in Dallas by experienced machinists.

These guys have been grinding camshafts for years. Be aware that the regrinding process can leave tolerances in the +/. The goal of these cams is for offer an inexpensive way to experience hydraulic roller power and durability! The camshafts profiles are reground from used OEM cores. They are cold vatted to clean any elements off and checked for straightness; if they need extra attention then their brought back to square.

Due to the nature of the grinding process the cams become small based circle. The higher the lift the greater the base small is reduced. Basically, the base circle and flanks of the lobes are reshaped to create the new profile. So, by the shear events the "bigger the cam" the greater the clearance. This works in favor for larger displacement application (larger strokes) needing a bigger cam. Always check you push rod length as I cannot advise you on the required dimension. The lobes and journals are polished and afterwards the camshaft is then dipped in hydraulic fluid, wrapped and boxed for a long shelf life. For years and when unpacked look fresh for use, but it is always good practice to examine parts that set for long periods of time. The picture is a generic photo for advertising purpose. It is not the cam you will receive, but showcases the finish these cams acquire.
