That car was super clean and had less than 500 miles on it when turned into a race car by the original owner. Back then I had almost zero tools needed to upgrade the chassis and zero knowledge of knowing how to go about it. A buddy of mine was selling a Pro Street 1982 Dodge Charger tat had a 4 link and 16-32 slicks on it. A way heavier car with the same combo it ran 10.0’s all day long. I changed it over to a powerglide instead of a 727 and did very well in that car. It still had the stock wheels on it when I bought it so a buddy redrilled a set of centerline wheels to five bolt 100mm pattern. It comes down to the reason I moved on from super stock springs was track prep. Our track manager was on a limited budget and the car worked great Friday night and cooler summer Sunday's. But when the track got hot consistently suffered.
