For a year I've been meaning to mention this on here.
Went to the dragstrip last year and was running a string of 12.40's and 12.50's, wich was odd since I had done some more mods and had previously run 12.30's. After driving home the car felt real sluggish down low. I finally figured out that the distributor bolt was loose (damn chrome). Reset the timing and everything was.
It got me thinking that I had only increased the timing at the upper rpms and load levels. I increased the timing at lower load levels and rpms, car felt more snappy around there. Nice little driveability increase.
