The importance of a torque plate

And to think of the millions of engines that came down Chrysler’s assembly line that never used a plate. That 5-10 HP could’ve helped

No way in hell lol they were soo cheap when it came to manufacturing, they could have started by tightening up their tolerances by even just 30% and their engines would have made WAY more power. There was another thread where someone posted tolerance specs from one of the Chrysler factories back in the late 60s and the allowable variance in compression ratio for a HP 440 was something like 9.3-10.2!! There's a 20+ HP difference right there. Explains why many classic Mopars either ran super strong or unexplainably weak when new. And why blueprinting Mopar engines can give such huge gains even without other mods. Same goes for rotating assembly balancing, deck machining, cylinder head casting, you name it if they could cheap out and save a cent they'd do it.
