How can I slow down 7 tenths?

Going to try some index racing this weekend. I normally run 10.30's so I'm too slow for the 10.0 class. I need to slow it down to run the 11.0 class. I'm going to remove the cold air box that is normally good for at least a tenth and then shift at 6000 instead of 6600. I have the motor pretty fat right now so if its hot and humid that might help too. Any other ideas on how I can slow this thing down? I should probably post this on a Chevy site to find out how they go slow.

You could try taking some timing out...or maybe a fixed throttle stop. I had a friend loose the secondary linkage off his double pump carb and that also slowed it down about .8.

If all else fails take a plug wire off, had a friend tell me last weekend he had a plug go bad and the car fell off .60. He checked the pipes with a heat gun and found the dead cylinder, replaced the plug and the car was right back where he was.

Hope you get a few time trials to get it right.

Good Luck!

Footbrake

Its a footbrake car with a low stall. I hold it at the line at around 2200 Rpm. Any more and it pushes me thru the lights. I need a converter bad. Then maybe I could run the 10.0 class.

Yeah I was thinking of just doing the fender thing. The only problem with that would be if the other guy was sandbagging also.

Dont forget to factor in the reaction time. If you have them covered on the tree you have the difference between the reation times to play with as well.

The secondary's deleted,or the fixed throttle stop would be the most consistant route
