Pete, as a Ford guy i'll proudly blame GM for that. They got the stock wheelbase rule thrown out for the Beretta, got to stretch the front end and move the rear wheels forward. They also got to use non-production based heads. Spread ports, symmetrical ports, then the front mounted belt drive distributor, then non production bore spacing.... at one time they used actual AR Boss 429 blocks in a GM Pro Stock car. And the Dodges were using a whole GM engine at one point.

And the same is happening to Stock and Super Stock bit by bit.
