    They look good. Did those others only look warped after you heated them up, or were they screwy from first mount?

    They sucked from the start Randy, We even had them shaved down to where they were flat but they still would not work. But I will say the other guys use them and they work pretty well for them. They just don't work on our light car. And I love your new car Rand Man.

    If that doesn't fix the problem, you'll just have to quit tipping the can as far.LOL

    Holy Guacamole! Have you figured out what caused that? Coil bind? Spring pressure? Bad casting?

    Interesting. Is that a weld bead around the bottom of the broken stand?

    Nope it was a brand new head. But there will be a weld bead cause we know a guy that can fix it.

    We had an issue with the crank trigger that changed the timing on that run so the cylinder that didn't fire filled with fuel and damage was created Dammit. At least that is what were thinking. I know what you guys are thinking but so far we have found no other damage.

    Well after all these months we finally got the head got the head back together. So while we were waiting we built a weight bar for the car to try to help with our traction problem. We also had a stud girdle built hopefully to cure our breaking rocker stud problem. Then the valve cover would not fit over the stud girdle:(:( Now we have to build a new valve cover. Now every thing is back together. Saturday is Tulsa's first test and tune so we planed to take the car out to see how everything works. BUT when we went to adjust the valves this morning plans changed. When we brought it up on TDC on the balancer the piston was not up all the way like when the piston was up the intake valve was open not good. So engine comes out and goes back to the engine builder Friday. God! I love race cars.

    Do you know for sure the balancer outer ring has not slipped? Common. Set the valves on #1 by watching the two rocker arms on #6, likewise by looking at all the other "buddy" cylinders as such:

    153
    624
    1s buddy is 6, 5s buddy is 2, 3s buddy is 4, etc,etc.

    You can drill and tap the crank and put set screws in between the balancer and crank.. I have had to do it on a big block and it has worked for over 100,000. Miles

    Finally got the engine back together and in the car this last week, All we got left is install the intake and hook up fuel lines. Plan on testing this coming Friday but of course it is suppose to rain. Thank's for asking Randy.

    We actually got the car all back together and running. Took it to Tulsa for some testing last Friday night and finally the car hooked up to the tack(100 lb weight bar done the trick) we were happy. Ok, the little car's first pass netted a 11.86 et after my partner(Driver) made a few mistakes getting brain and foot to hook up with gas pedal so probably killed a few tenths or so. So while getting ready for next pass driver notices fuel cap missing Opps! Fueling the car was my job. Well I took the 5th and I no nothing. We all looked up and down the track and never found it so we were done for the night.:(:( I call the car little because here what it looks like up next to another SDRA car. This was a photo opp last year and not racing. Next time sdra car test session 014.JPG

    Wow! a 6.80 1/8 mile ET puts you in the 10's. Great performance for the little car. What's up with the SDRA cars this year?
