no mention of a converter? i'd say low 14s as it sits...Low 13s? No. High 13s? Maybe, on the top of its game.
13.6 here with stock port j-heads, 9.7:1cr, eddie 650carb, .480lift/280*dur hyd cam, 3.91, 3500stall, headers, 29.5" tall slicks (wayy...way to tall).
According to the dyno it was extremely lean with that tune (since changed), shorter tires next outing, better fuel, i may run faster.. 3500stall with 3.91s on the street, even with this little engine is pretty fun
