Tim, I am very new to this, so much so I havent build a kit since I was a kid. I just joined the forum and Im still in the planning stages. I like large scale car so my first attempt at this will be a 1/12 foose camaro, set up to x275 specs. I always plan ahead and never shoot from the hip on any builds, and the research has me baffled on specs alone. I know the x275 class is fairly new class, but Im finding different rules in different parts of the country. Maryland, being the closest state to me with guidelines, will most likely be the specs I build the car to. The only direction I have at the moment is a single turbo small block with a ladder bar suspension. Im still researching component dimensions, and with alot of searching, I finally found specs for the ford 9" third member bolt pattern. So if this is a sign, this is gonna take awhile LOL.
