70 dart 470 ci drag car build.

I headed over to Tim's for a couple hours after resurfacing the intake manifold, made some gaskets for the plenum and hooked all back up.
Left the tune in the carb alone. He locked out the distributor and we Finished the piston break in and then made a few test runs.
1st test just to 5250
2nd to 5750
3rd was to 6350 I believe with some timing out was 611.
4th with more timing.
We have some tuning left it was very rich and still need to dial it in but....
