The Midwest mods from the 70'/80's above were not IMCA. Each one was garage built, most with front straight axle, quick change rears.
The frames had to be 2x4 or 2x3. There were no two cars alike. (Pretty much like our brass scratchbuilds). Each track had
their own local sanctioning club. Harry's & my track had a cubic inch limit, 10" engine setback,105" wheelbase & minimum weight.
Allied Auto Racing, down the road was similar with a 12" setback, no minimum weight, 99" wheelbase & unlimited engine size.
Any make or size tire could be run. All required one carb. All crash damage had to be repaired, Could only be primer one night.
There were big block Chevys, Fords, Hemis & even a Ford Cammer or two at Allied. Cars were leaf springs, coil overs, cantilevers,
mono-leafs, torsion bar & combinations of each. Innovation was KING in those days. So it was a long way from IMCA.
Late model racing took over from the unlimited modifieds & now they only run as a vintage club class on selected nights.
