The letters 'HP' on the engine id plate designates a 'High Performance' engine. What goodies are put in above a standard 440 to make it High performance? Engine is for a '69.

Also wondering if it is common for the upside-down 'A' to appear (20 thou over) on a '69 440 engine.

Struggling to find a set of piston rings for this too  :confused: :confused: :confused:
"An aggressive exterior with power to match was enough to pull in the performance boys-especially when abetted by a pair of pipes blaring out the back, and brawny red-sidewall rubber hitting the pavement."
