FAQ
Are roller lifters better than hydraulic?
The choice between roller lifters and hydraulic lifters depends on specific engine requirements and preferences. Roller lifters, such as those in Howards 91161 retro-fit hydraulic roller lifter set, are known for reduced friction and enhanced valvetrain stability, potentially offering improved performance at higher RPMs. Hydraulic lifters, on the other hand, are known for ease of maintenance and self-adjustment. The decision between the two depends on factors like engine type, usage, and desired performance characteristics.
What is the difference between a solid lifter cam and a hydraulic lifter cam?
The primary difference between a solid lifter cam and a hydraulic lifter cam lies in the lifters and their valvetrain operation. Solid lifters have no internal hydraulic components, requiring periodic adjustments for valve lash, making them suitable for high-performance applications. Hydraulic lifters, like those in the Howards 91161 retro-fit hydraulic roller lifter set, feature internal valving for self-adjustment, reducing the need for regular adjustments and providing a smoother valvetrain operation, making them suitable for street and performance applications with less maintenance.
Can you use roller rockers with a hydraulic cam?
Yes, it is common and acceptable to use roller rockers with a hydraulic cam. Roller rockers, when paired with a hydraulic cam, can further improve valvetrain efficiency and reduce friction. The combination of a hydraulic cam and roller rockers enhances the overall performance and longevity of the valvetrain components. This compatibility offers flexibility in customizing your engine setup to achieve optimal performance and efficiency, giving enthusiasts the versatility they need in their builds.

Motor Vehicles
WARNING: Motor vehicles contain fuel, oils and fluids, battery posts, terminals and related accessories which contain lead and lead compounds and other chemicals known to the State of California to cause cancer, birth defects and other reproductive harm. These chemicals are found in vehicles, vehicle parts and accessories, both new and as replacements. When being serviced, these vehicles generate used oil, waste fluids, grease, fumes and particulates, all known to the State of California to cause cancer, birth defects, and reproductive harm.
Tools:
WARNING: Some dust created by power sanding, sawing, grinding, drilling, and other construction activities contains chemicals known to the State of California to cause cancer and birth defects or other reproductive harm. Some examples of these chemicals are: lead from lead-based paints, crystalline silica from bricks and cement and other masonry products, and arsenic and chromium from chemically treated lumber. Your risk from exposure to these chemicals varies, depending on how often you do this type of work. To reduce your exposure, work in a well-ventilated area and with approved safety equipment, such as dust masks that are specially designed to filter out microscopic particles.
