You have to run the type engine that was available from the factory in that car with all the stock heads,intake carbs and exhaust manifolds. Max size exhaust
system is 2 1/2 inches with full factory system and factory looking type mufflers. Must run on factory size and type tires that were available on car. They run reproduction tires bias ply and F-60-15 on this Hemicuda.
Engine wise you can do anything as far as stroke...cubic inches camshaft...cylinder head and manifold porting...compression. Must pull a certain vac. at idle to sound somewhat stock. Some of the guys at top of class running mid-high 9 second ET's at over 140 MPH on those stock type tires!!
Get caught with Nitrous and banned forever plus sent to Mars!!!
Have seen them run and it is wild what they can do! No major awards or money for winner just bragging rights!
