We run Menscer valved Afcos on one car. Makes around 850. Runs with radials and Cal Tracks. Very consistent 1.38 60@3750lbs, 3.55 rear. They've been very good. Great support as well. The other car runs 10.5 bias slick, ladder bar, making around 900. It has Afco doubles up front. They have been revalved 50% stiffer. The rears are an old set of Koni doubles stock valving. Car also works pretty well been 1.250 60@3350lbs foot brake.
