I hind sight, I realize I was premature is saying I would close out the Super 10 series. At the time of my "closing it out statement" I did not consider the ongoing changes that die in the wool hot rodders will always be making.
In addition, a broken intake valve was the farthest thing from my mind.
So, we move on.
First, the broken intake valve is my fault. I knew the valve to piston clearance was border-line too close yet thought it would be OK. Also, more than once I let the engine get away from me in the water. The 327 likes RPM and in the water the gas pedal just kinda falls away from my foot
It will get on an 8800 chip before you can say don't do it.
Lessons are learned and adjustments made. The rebuilt engine will have "enough" clearance and the driver will do a better job of RPM control.
Second, the 6.0 rear gear is slightly too much at the finish line. I am changing to a 5.86 gear and that will lower the finish line RPM by about 200.
The 6.0 gear was a Strange/US gear that I sent to have REM and Cryo treated.
With the 5.86 I decided on a Richmond 9310 series and installed it out of the box. I like the Richmond better. It setup right on the money and has a good pattern.

Photo # 107 shows the dial indicator reading that means the pinion depth is exactly as etched on the pinion.

Photo #110 shows desirable gear pattern.
And another in hind sight observation. My race experience with a Chevy 12 bolt has been good. I have built and installed a number of 12 bolts and all give good service.
However, because of the steep gear need with the Super 10 the 12 bolt pinion becomes very small. I now realize a 9" Ford would be a better choice when selecting the very low ratios.
