I'm one of those who used to run a TR on the street and wondered what all the fuss was about. Tuned right, or as right as I could get it, it certainly didn't lack for anything. One of those gigantor UR19 types might lose lotsa torque down low, but my old Offy (and especially the Weiand) did everything better than the typical high rise single plane. If you look around, you might find some magazine articles that show reasonably sized TRs outperforming everything else on the dyno, all around, including useable torque. Where they failed was in efficient use of space.
The 1992 iteration of my faithful ole Boss 302 certainly had a lot better street manners with the TR, getting something like 18 more ft. lbs. of max torque at almost 500 less RPM (more useable torque all around the tach), and the top-end power was gratifying, to say the least.
Tuned well, I believe you would be quite happy with a Weiand Tunnel-Ram. Maybe I had dumb luck, so YMMV.
