Re: Dumbo The Flying Elephant
I have to make an adapter to keep the mic centered on the valve stem. Plus I have the added fun of checking with top locks, standard locks, -.050 locks, and +.050 locks to get the best setup for the head. Man I love this game!! It’s all worth it when the light come on in our lane in a heads -up race, and when it doesn’t I have a new roadmap to follow and guide me.

Re: Dumbo The Flying Elephant
I finally got the stuff made and was able to figure installed height. The kool part is I was instructed to get several different sets of valve locks. The standard, the +.050, the -.050, and the top lock. It moves the installed height around and with the help of shims I will be able to get to my coil bind target number on each spring. I’m hoping to get to size to plus .005” on installation height.
A tip of the Hat to all of the cylinder head folks, it’s not easy just to get the installed height correct, past Tech, and run hard all the way to the Finnish line. The real good cylinder head people are a bargain. Last edited by Larry Hill; 02-05-2024 at 07:56 PM. Reason: Billy was having to much fun! |

Re: Dumbo The Flying Elephant
I’m getting to use my Christmas present from Patsy. It’s a plastic tray from Summit that holds all of the valve train parts in each cylinder’s location.

Re: Dumbo The Flying Elephant
Thanks Billy. I think a little quicker than I type. I will change it.

Re: Dumbo The Flying Elephant
Once I got the heads mocked up now waiting on parts. We had to withdraw from Florida.

Re: Dumbo The Flying Elephant
We have been working on some secret squirrel stuff. More latter but not to much.

Reason is locks only clamp on the valve stem below the groove, the ID of the lock is larger above the groove. |

Re: Dumbo The Flying Elephant
Thanks I will check that.
Spoke with someone that had some thoughts on why the head leaked coolant in to the spark plug bore. Coolant casting core flotation. I wonder why it took two seasons of racing to appear on this head an only one season to cause a problem on the odd cylinder head. One of life’s little mysteries. |
