Welcome Dave
Now compare the 72 Low compression motor to a 440 that some may build .. 500 HP range and the value of breathing really shows
Smaller differences on the LC motor and major differences on the Higher Compression motor with some Mods many do that are well within a lot of peoples range and are not a race engine.
Even if you wouldn't invest $1.5 to 2K more for the 500 HP build vs your LC motor rebuild (diff being heads, manifold, carb vs stock) you would most likely bump up the compression and have a MP electronic ignition even if you stay with stock rebuilt heads, intake and carb .. your HP would move up based on the compression alone and the differences would be more substantial than the 7.5 compression test engine.
Sorry it's hard to read but hopefully you can adjust screen size to magnify .. my spreadsheet was getting pretty crowded
10-20 TQ and HP jumps (more with more compression) vs 50 - 75 TQ and HP jumps
