Altereds in the Old Daze had short wheelbases, like 99". Very hard to drive. With the current nostalgia movement, there are 2 kinds of altereds: the originals with short wheel base (like the Rat Trap or the Wing) and Transformers, which are based on modern day F/C chassis. Even tho altereds are lighter than a F/C they are not streamlined, and still hard to drive because of that. Transformers like Tims' car are still altereds, just "modern day". They don't have the downforce of a F/C. Hartman said after he made the 4 second run that the car got a little out of shape about half way down but he was able to drive out of it. I'd like to know what the 1000' times were on Hartmans' run and the 1/8 mile times as well.
