Quick update.
Since changing to a 5400rpm stall, this engine is waking up nicely. I have taken the diff head out and getting 4.11:1 gears installed. This will get the blood pumping again.
Here are a couple of clips of us racing on a non prepped goat track 1/8' mile. wouldnt even hook up so I put on a smoke show for the crowd. A fellow hotrodder with 300hp less bet me to first place

It was quite scary in the breaking area even at 107mph!!!!
Cheers
