it is a barracuda with 440/auto 3:91.I have it tuned as far as I can go with my timming and fuel/jetting. the plugs look good but show a little to much timming as far as the FBO site considers. I don't like the idle on the 850 dp,everything else is good to great.I have a stumble but figure pump cam may fix that. I just can't seem to get the idle peged down.
highest vac reading is 13-14 with 6.5 pv.
