So the "Battle of the imports" is only based on chassis, not engine?
Thanks for the comments, guys.
If you have an imported car with a domestic engine you can only compete in bracket racing, not a specific class. Then they take the quickest 16 cars out of all the bracket racers and form Quick 16 Bracket so that fast cars wouldn't have to race against the really slow bracket racers. Let me tell you there were a bunch of slow cars there....but they had fun, too.
I ran 9.44 last year when the engine leaned out and burned pistons. My current tune is still too rich, but it's safe.
