I would tend to say that tose cams are bleeding off too much compression from that tiny little motor. those pistons put it at around 10.5:1 ratio with that head. those cams are reletively large on the exhaust side, and are designed for minimal crossover road race profiles. down low, the b16 doesnt move a ton of air to begin with, and at the compression it has the large primary lobes could possibly be too much for that motor to handle. once it gets into the high end on the graph the power seems to build nicely and carry very far. I would think some ctr pistions in there, and possibly some head work may help that motor a lot! thats just my theory tho.
