carb jetting for 1/4 mile gurus

I think 84's are good, but w/o power valves. Thats all I run on my 433" small block. 9.50's 9.60's @ 138. But I have a friend with Iron w-2's and he is in the 90's with his combo. again no power valves. Remember adjust only one thing, get a "best base line" and move from there. Fuel then timing, not both at once...Timing about 34 degrees total. Good start. Fuel demands will change depending on the vacuum signal on the carb. In other words, engine sealing efficiency will affect A/F ratios. Enjoy the track time..!
