Roller cam. Hydraulic vs. Mechanical in a 340

The roller Hyd. lifter is heavy and gives up when the rpm rises high. A loose of performance occurs. At the expense of the set up, a solid roller is better and much more productive.

Many people use a Hyd.roller thinking there going to rev to 6500+ and stomp some butt into the floor. They get very upset when there 3600+ lbs. heavy thing is loaded up with gas and the driver, now 4K plus.

See the math? It gets worse in a stroker engine that has stock Edelbrock heads & ports. So much is left on the table while trying to move fat *** (car) down the road.

They think it pulls but when a lesser engine stomps there hind 1/4’s into a mud hole.....
