I have cheap CE 3 ways on my street/strip Dart, it's powered by a pump gas 408. It's gone 1.38 60' several times and normally goes 1.39-1.40 on MT ET Street Radials. Most here will you to stay away from them, but they seem to work for me, your results may vary though. I'd like to see how my car would react to a "better" shock but the costs are to high for me to try.
