1967 GTO delivery a few weeks back. Customer loves it. Had to do some unusual carburetor tuning. Transfer slot fuel feed was out in left field at 0.117". Restricted it down to 0.076" to get rid of the extreme rich cruise mixture or 10.4:1 AFR. went from 82 square jetted out of the box to 78 primary and 93 secondary coupled with a 10.5 power valve and its spot on. 14.1 cruise (e10 fuel) 13.2 idle and 11.2 WOT (again e10 fuel!) Fuel curve is t**s. Went to a 0.037 squirter also from 0.028. Thanks to Otto Tharp for the old H-O Racing headers!
