Okay so I just did a new set up in sig. I'm sure I will need the BR7EF's what is the part number I need and what should I gap them at? I plan on keep upping the jets until I run out of fuel. I'm running the the racetronix pump and hot wire kit and an nos plate kit running off the rail. What shot would you guys say I should run a BR8EF and do you think I will be running out of fuel? Now can someone verify this is correct or tell me the proper procedure for plug reading. Get too the track change the plugs. Should I push the car to the line because everyone knows you can be in the pits for a while with your car idling. Being I have a th350 and it's not good too throw it in neutral once I cross the traps still wot I shut it down and coast off the track. Then I pull the plugs or wait 30 mins I don't know how much the guys at the track will like that being pulled on the side of the return road. In any case that I don't make it all the way off can I start it back up and idle to a safe spot or pits? Thanks guys
