I do not want to change Enduro at all, I want a separate class. And Ernie, if you want that Impala built for the track, I will help you anytime.

CSC does roll bar kits cheap, if anybody needs help I can be of assistance

currently building 92 firebird for enduro, the motor is tbi, now the question is, is this motor ok to  run with all the electronics, has anyone else ran this type of set up. also looking for a cage and seat for this car.

Overcoming the speed limiter in TBI equipped F-bodies - ThirdGen.org

It works just fine, except for the limiter like Jimmy said. Open the nose up huge, for airflow. You can take the front bars up to the idler and steer box, tie them in to the strut towers and open them up for more airflow. We had all our heat issues gone by mid season, just bad luck rest of the year with engine failures (budget constraints). Run mechanical fan setups, ignore the electric in these rides.  The 160 guys a win under their belts and many top tens. They have a very good machine built, probably wouldnt hurt to cantact them as well.
