So your problem is not lack of performance at high rpm at all.  That's less
than 3000 rpm, not even to the torque peak with the factory cam.  A wilder
camshaft isn't likely to improve much on power/torque at such low rpm.

And now you know why the original OD is so nice.  At 70 mph, you just flip
the switch and hey, presto you're in passing gear.  Or drop a shift into 3rd
OD and you're right at the power peak (with the stock engine).
