I tell you what if you find a 540 that makes 1300 hp then I would like to see it. Our motor is a 50,000.00 dollar 632 that we got some deals on and it makes 1300 hp on the motor. I am not sure if you fully understand what is involved in makeing that kind of power. I have been doing this for a while and the ads you see in the paper are bullshit. I have never seen a 540 make that kind of HP on motor. Also the cars that run in our class are all 6 and 7 sec cars and I dont know anyone that has a motor smaller than 572 with spray dripping off of it. Now I did see a 1900 lb car with a small block and 800 hp of spray on it run 7.70 but I doubt it made that much hp. Anyway as far as classes go they will never allow them in to Pro Stock. That is why thaey have their own classes. The cars in Pro Stock have so many rules to follow and are under so many constraints that they will never change it for imports. That is why Pro Stock racing is so close because the cars are almost identical and they have very strick rules to follow. Who cares who says what. This is racing. That is like the NASCAR/DRAG Racing arguments. Also Pro Stock cars are limited to 500 cubic inches not 600. Again this is not ment to put anyones opinions down or anything. Just to represent some facts and some of my opinions.
