Phil, we tested an HP950 on the dyno at KRE, back to back against my 1977 Pontiac q-jet. It made 2 LESS hp! I also borrowed one last year for some street/strip testing, ran OK, not nearly as smooth on the primary side as my Q-jet, but fine at full throttle. They seem to be pretty decent units as delivered, the one I borrowed could have used some improvements at light/part throttle as there was a slight, but noticable transition onto the main system. It wasn't mine so I didn't start messing with restrictions/air bleeds, but I'm sure we could have made some improvments.
We're running a pretty long "backlog" on rebuilding/restorations, keep that in mind with the 67 q-jets, you may want to get them in line early.....thanks....Cliff
