340 in a 68 Barracuda. Ported iron heads by lead69. Air Gap. IIRC it’s a measured 10.5:1. Mother Thumper cam. QF 750 Brawler. TTI 1.625/1.750 step headers. 4 speed with 3.23 gears.
The carb was right out of the box and as you can see it was P-I-G rich. The only things I didn’t change are the main air bleed and the idle air bleed. Everything else was changed.
It’s IMO about as good as it can get at idle and cruise, and it’s a bit fat at WOT but that’s hard to see in the pictures.
So it was a good day. Went through some brass, but I’m happy where it is for now. Later I’ll tune it for WOT.
