Drag racing classes?

So the classes are heads-up, not handicapped?
Heads up and lots of politics .I mainly go to race my internet freinds from another website and to challenge myself for a better ET each time.Its usually the same old bunch for the most part at all the events.Cars running 20's all the way to 8's in the 1/4.Its kinda screwed up ,but its just for fun .I run in the mid to low 11's on 8 inch slicks and i am racing backhalfed Chevys that run 9's and low 10's usually ,so you can guess what happens.The cars in the class i should be in run 12's to 14's ,so thats why they move me to COMP class ,pretty neat huh ? Did i mention im usually the only smallblock Mopar out of 200+ cars each time ? Not trying to hyjack this guys thread , i just wanted to tell you and him a little about this realm of racing ...
