Running higher timing helps the car launch harder but might be harmful down track...

Many years ago a friend I knew had a very famous and winning BB Chevy II SS'er and it came with a little instruction sheet for the timing..

It was a 396 with closed chamber heads and they liked high timing..

The sheet spec'd 54 degrees and was retarded with each gear change. It was a Turbo 400.....

I used to use drastically lower timing when track conditions were not good to try and hook better....it did make a difference....so it would work the other way too.

Has to be tried to see if it works....the ET slip tells the story..
