Hoosier 275……………is that making a comeback or just what you decided to use ?
Are the rules for Ultra always set up to keep the cubes at a limit for Mopars ?

MT changed the tire to the SS version. Most people stocked up on the older tire and ran that all of 2016. For 2017 the SS version was all that was going to be legal. The SS is not as good as the original. People complained and a list of acceptable tires was allowed. The Hoosier Carrys a 50lb weight penalty. Yes the rules limit Mopar big block to 540.
Al I don't know the NA weight. The rules are on YB in the Cecil county section.
