When a crank or cam is polished on one of these machines, it uses about one inch of tape per journal, so fresh abrasive is used for every polishing job, but because it's such a small amount, many users say they've saved money. "One PER reported a 50-75 percent savings in the cost of tape vs. belts," Barton says.

Now replace the camshaft with the original cam for your intake valve so it just starts to open the valve. If it doesn't drop in you may have to grind a little off the cam. The intake should close one thirde to halfway down. The best way to grind the cams is to hold the ends of the shaft and rotate it into the grinding wheel.

When comparing mechanical roller to hydraulic roller cam specs, remember to subtract the lash from the mechanical roller lifter's net valve lift numbers. So if the cam has a gross valve lift of 0.550 but requires 0.020-inch lash, the net valve lift is really 0.530 inches.

But now, a cam around 216/224 degrees at 0.050 with a lift of around 0.460/0.470 and a lobe separation of 110 to 112 degrees would be a good choice. This cam creates decent low-speed and mid-range torque to accelerate the car because it has a …

For a single overhead cam, I may want to keep the cam profile and change the lobe centers. I have a jig to measure existing cams and if I use a follower on the cam the same diameter as the wheel, the angle and X coordinates measurements should be able to duplicate the cam on the grinder.

Hi folks, After a disappointing search for hotter cams than wldr's here in Europe, I decided to build an own cam grinding machine. And finally, just two short years later I finished 2 cam sets (one 294°set for my street stroker and a asymetric 312°set for a 45 racer, both 10mm/0,393in lift) with the cut off - press on - adjust - and weld on method.

The surface lay generated by grinding would cause abrasion to the bearing surfaces if left unpolished. By polishing in the direction shown in either the figure 3 or 4, the surface lay is reversed by the polishing operation removing fuzz created by grinding and leaving a surface lay which will not abrade the bearing surface.

It might be possible to make one from an existing cylindrical grinder particularly if CNC controls are employed to coordinate wheelhead with cam axis rotation. Mount the head slide in ball way bearings. Add a high accuracy servo/ballscrew to the wheel head axis. Add a control with custom software etc. Yup. It might be very possible.

That means we grind them down 0.200" and expect the engine to make 500 hp and live! In order to build a low deck 470 Chrysler, the mains on the 440" shaft are turned down 0.125" so the crank will fit a 400 block and the rods are offset ground down to 2.200" instead of the original 2.375".
