late model rules

[mud dog]

I am having trouble getting the rules page up. I have a 430 steal block with aluminum 23 degree heads and run alcohol. Is this legal for dublin or fayetteville?

Thanks alot for the rules post. I was hoping to come down south but with all the tracks besides clarys having 365 ci rule I guess i will have to stay up nort:smellie17: h.

At Dublin, you are not restricted to 365 cubic inches. In fact, you would be hard pressed to find a car in SLM running that small of an engine. Also, you must run racing gasoline, not alcohol. Otherwise, you only have to meet weight requirements for engine installed.
