Can I replace a flat tappet cam with a roller cam?

Flat-tappet cam lobes are ground at a very slight angle to prevent the cam from moving. Roller cams cannot be machined this way, so a roller-cam button is employed to limit cam movement. The spec for this is 0.003 to 0.005 inch.

Can I run roller lifters on a flat tappet cam?

It is possible to run hydraulic flat-tappet lifters on a solid flat-tappet cam, and hydraulic roller lifters on a mechanical roller cam. Running hydraulic lifters on a solid grind raises the rpm points at which peak power and torque occur compared to using solid lifters on the same solid cam.

What is the difference between a hydraulic cam and a roller cam?

At first glance it appears the real advantage to a hydraulic-roller cam is greater lift. In truth, the real advantage of a hydraulic- or mechanical-roller cam is that we can hold the valve open longer, which gives us greater airflow and improved exhaust scavenging.

What does a flat tappet cam mean?

See all 30 photos A flat tappet camshaft is set up where the lobe and lifter ride against each other where the lifter spins on the cam lobe. The lifter must spin on the lobe to prevent destructive and unnecessary wear. Flat tappet cam break-in is critical to long life.

Which is better a roller camshaft or a tappet Cam?

Unfortunately, roller camshaft systems cost more than a flat tappet cam and lifters. Much of the added cost is due to the lifters. However, roller tappets can be re-used, where as flat tappets cannot be re-used. If you tear down your engines frequently, the rollers can be used over and over again provided they are not damaged or show signs of wear.

Which is better a roller cam or a flat Cam?

If a cam profile has more ” area under the curve ,” it has the potential to make more power. Roller profiles can be more “aggressive” and accelerate the tappet more than a flat tappet profile. Flat tappet profiles can only be shaped up to the point where the tappet “digs into” the profile.

Which is better a roller tappet or a flat tappet?

Roller profiles can be more “aggressive” and accelerate the tappet more than a flat tappet profile. Flat tappet profiles can only be shaped up to the point where the tappet “digs into” the profile. Roller tappet profiles are not limited by this condition-so much that even “inverted radius” profiles are possible.

What should the EndPlay be on a tappet camshaft?

COMP Cams suggests setting the endplay between .005- and .010-inch, using a dial indicator to measure front to back movement of the camshaft. After the endplay checks out within COMP Cam’s spec, we remove the outer timing chain cover plate, and then prepare to install the timing chain.
