Dumbo The Flying Elephant

So what ever made Stock Eliminator an entry level class? LMAO!
I sincerely hope that the twenty-somethings embrace what racers like Larry represent to this craft.

For me it’s an investment because I’ve had the pleasure of building a new engine after a major failure. To put things in perspective the price of the tester is less than a set of lifters for Dumbo.
With the scarcity of parts and no parts support from MoPar I have to be conservative with everything, mostly heads and blocks. With RPM capabilities of the engine I cannot afford a .010 error on the wrong side. I’m just trying to make my stuff last a lifetime. The cost of the tester will be reduced when we quit racing and liquidate parts and tooling.

Before Jerry passed we would sometimes split the cost of something that we both needed for the advancement of our racing.

Just like my old friend would often say “All the experts don’t live out of town” but I need to add “but some of the equipment does “

This afternoon I finished the heads. The worst installed height was +.008 above target. The rest were closer. The cool part about the print out I was able to put the slightly stronger springs on the heavier valves and the weaker springs on the lighter stuff. I sure hope all of this prep work helps. Tomorrow I’ll check lift at the lifter, lift at the valve, and rocker arm ratio.

Life got in the way of racing and I accomplished zero progress on the car. And so it goes!

Don't I know it.

It looks like the valve lift will be .009" from maximum. The next cam we have made we will see if we can add .005'' to the lift.
My numbers are theoretically right now: I took lift at lifter and multiplied by NHRA rocker Specifications.

Quiet day was spent in the shop with just me and Dumbo. Some days it’s difficult to know who’s who. Only got three rocker shafts installed. Every one had to be redone one took three times. Poor visibility on parts and gravity is not your friend and my fingers are to big. And so it goes
