People talk about not allowing aluminum heads in if that engine never came with them. Well explain the GT classes allowing rear wheel drives and engine other than 4 cylinders!

James The GT classes rules are separate from the traditional Super Stock Classes and were made to accommodate the next step in modern racing in the 80s at that time .I feel the GT class has made a special input for Super Stock and FJ smith started the front-wheel to rear-wheel cars as part of the Progression of Super Stock it has been a significant positive effect in Modern racing since then> Some changes to rules have to be made to accommodate the future of each combination
