273 how far below deck are the stock pistons?

I've was reading my Mopar Performance Engines 8th Edition and it states that 64-67 has a pin height of 1.79", 0.031" in the hole and 68-69 has a pin height of 1.82", 0.001" down the hole. Don't know how accurate this info is but soon find out when I tear into my engine.
