X275 is a heads-up class designed for small tire, single power adder small block and big block engine combinations to compete on the eighth mile. Centrifugal Superchargers, Turbochargers and Nitrous Combinations are restricted to specific dimensions/sizes to ensure overall class parity. All entries have the option to run either a 275 drag radial tire or 28 inch by 10.6 inch bias slick on any type of rear suspension.
