1972 280SE 4.5 Dyno Performance Upgrades


I recently acquired a '72 280SE 4.5 (auto trans) which does not have any specific engine or driveline performance issues. However, it doesn't deliver the overall performance that is expected based on published historical specs. I'm getting it dyno'd and recording compression next week to get a baseline before proceeding any further.

Questions: (1) Any other dyno charts out there I can use for comparison of rear-wheel numbers?, and (2): If I have a $600 parts budget to increase engine output, where should I spend it if I'm willing to upgrade parts and eliminate things that limit performance?

I'm not trying to turn into a tire-smoking beast, but would like to let the 4.5 get up run a little more freely. I'm happy to share/post my dyno chart next week for the benefit of the forum.
