Altered wheel base cars never ran in the "Gas Classes". 2 rules that a lot of people have forgotten are: center of crankshaft can not be more than 24" from the ground , and the other is that the rocker panel can not be higher than the center of the rear wheel. Those are the NHRA rules from back when Gassers ruled. I retired my Chrysler powered Willys in 1968 and still own it.
