Dan, may I ask if you live in NC and if so where? The reason I ask is I may need to pick your brain on roll cage info. I am building a vintage type LSR as a 1933 Ford Vicky Hi Boy.... I wanted to run a 255 SBC motor but just found out that the bore is to small to get the valve size and runner size to make the HP I want,, unless I spend more on the heads than the entire body and chassis cost... I Thought the cage was to built for the speed I would run the car, not the current record of the class,,, from what I think I just read ... say I build a C/CGALT car and I only plan on going 130 mph , but the current record is say 159 mph do I have to go by the safety rules for the 159 mph or the rules for the speed I am going to run?
Thanks
Charles
