67 camaro with Peter Fedun SS record holding motor. videoed too. Their carb cost over $1000 for cryin out loud. But think what you want. It changes nothing. Did you ever try running a 4000Lb plus race car?
L2355Fs should be zero deck but are often .015 to .035 off that due to factory tolerences. Often side to side there is quite a difference. i have though had two that were within .002. Pretty rare though.
