I remember the first test & tune os the season I went too. Was a 69 Charger, 440-4speed. High performance this and that, 4.30 rears, M&H racemaster slicks, blah blah.
Consistent mid 11 car. Then all the sudden I blew the tires off and went a 14 something at some killer mph. Anyways got back in line. Same thing. Hmmmm. Got
back in line, and for a third time, same damn thing. Went back to my buddies truck where I kept spare parts, jack stands, floor jack, and my M&H's still
sitting in the back of the truck.
