The reason they run rat motors in Pro Stock is because the motors have to be NA, thus a need for bigger cubic inches to make power and I'm pretty sure they don't run turbo 4 cylinder motors in NHRA Pro Stock last time I checked but I can be wrong. You can make a lot more power with a turbo big block than a 4 cylinder, but trying to hook up all that power is another story...
