I guess I'm not seeing what you're seeing..... I looked on the Federated Auto Parts Raceway site and I didn't see much except for some weight breaks for the crate engine and of course they say "steel" block.. so I guess if I have an iron block I'm ok. What morons they want this class to become some sort of crate engine carnival good for them... I wonder if the Mexicans who put them together will be buying any tickets?
