Looking for some insight

Those are great street tires; great for sliding, for power-turns, and spinning to past the speed-limit anywhere in Manitoba, possibly anywhere in Canada. Super predictable when sliding around turns in second gear.
But I get 2.4plus 60fts out of them,lol, so terrible on the line.
At one time, my engine was similar to yours but with Edelbrock heads and at 3650 went 106, with a 223/230/110 cam@900ft elevation. The ET was 12.9;spinning most of the way.
