http://supercarraces.com/phpBB3/index.phpJohn, FAST rules were a great foundation but there were a couple tweaks we made that we thought would help build a larger racer base. The block rule is a biggie, which first started with the lack of available Ford 427 blocks and then snowballed. Then the carb rule was modified to open the door to guys thinking their car is not competitve due to a small cfm OE carb (think 383 A bodies
).
