440 Valvetrain Issues.....Questions

Very nice "threewood". I just sat back and looked this whole post over. I do have one question as to when you ordered your kit from B3racing. What info did you give him so he knew what to send you ? Thanks , Ron

Custom Kit Instructions

Measure the distance between the combination square and the tip of the valve stem, when the valve is fully seated, using a caliper, feeler gages, or other accurate measuring device. Be sure the square is resting on top of the rocker shaft and the blade is on the same angle as the valve stem or valve spring. Just align the ruler edge with the edge of the spring and measure from the square to the top of the spring retainer. Then, measure the distance from the valve tip to the top of the retainer and subtract that number from the square-to-retainer measurement. The measurement can also be taken directly to the tip of the valve but can be more difficult.

1. Engine type, i.e. BB, SB, Hemi, S6

2. Cylinder head type, i.e. OEM, Edelbrock RPM, Mopar Stage 6, Indy 440-1, etc.

3. The measured distance between the top of the rocker shaft and the valve tip of one intake and one exhaust. (FIG. A)

4. The measured distance from the rocker shaft and the valve stem. (FIG. B)

5. The measured distance between the rocker arm bore and the roller tip. (FIG. C)

6. The rocker shaft diameter. (if not .875)

7. The diameter of the roller on the rocker tip.

8. Intake and exhaust lobe lift from cam card and valve lash.

9. Rocker arm brand, offset and ratio.

10. Name, phone number, and shipping address.

Up and running very well. It seems to be oiling the valve tips fine. The oil holes for the pushrods dribble out the back behind the pushrod cups at idle. When it is revved up oil gets to the cups as I witnessed the pushrods turning yellow from the oil. 45psi at hot idle. All the pushrods are rotating. Hopefully this setup is solid.

Update from Crane...

Mark,
We have sent a couple out for a metallurgy test. Regardless of the results, we are going to replace the rockers for you. We are waiting for rockers we are currently making to come back from the nitride treatment. We should have them ready in the next week or so. Hopefully we will know the results of the testing by then so we would have a good idea on what happened. I apologize for it taking this long but it happened to line up with a time we are out of these rockers. I will let you know when they are ready to ship.

Thanks, Robert
