Almost back together
 
3 pistons, (how the hell does 2 screws destroy 3 pistons???) 4 valves, $400 in head welding / guides / milling repair, touch hone block, rings / bearings / gaskets.. normal freshing stuff.. I'm at $2900 not counting time and gas to run things 75 miles to and from the machine shop.

Lesson learned: make shure those damn squirter screws have a touch of locktite on them, and check them FREQUENTLY anyways!!!

This motor IS posessed!!!!!!!!!!!!!!!!!!!!!!!!!!

I started mine to pull it off the trailer sat and it had a strange whisle . Looked down the carb and there was a leaf in it . Thought about your squirter deal .

Glad to hear it is getting some love, but man, those are some expensive screws. You'll be back at it in no time.

I would be very interested in a chassis dyno number from it.

She is making noise. Have a ADRA race friday night :) Truck is ready!!!
If Rich doesn't tech I'll go off the stop again and see if the machnist 'trick' valve job helps or hurts LO. Has just a touch more compression (from milling the heads now 13.7 instead of 13.5). Because I'm not spinning it up and the convertor is a bit tight,, I put 1.5 more degrees advance in the cam this time.

Now just have to make 3 races and it will be Dune season again.

Marv, I know it is more money, but man, I bet that thing would like E85 :) Might be more consistant too in the heat.

Welp, 10.786 @ 121.5 in 3400' air. Picked up a litle MPH and the 60' is now as good as my Nova was when it was a 10.5 package. 1.43 sixty is rather surprising to me. This thing is not that well set up. Unfortunately I dialed 10.79 on that 10.78 pass so it was a short night. But the ol girl is back doing her job. Now it's time to start getting the sand rail ready for November
