Maybe yours is filled with concrete? |

Racers sometimes fill blocks with epoxy or concrete which can make them heavy!
My NOS 427 block (1972 date code) weighed just a hair over 200 pounds. Any 427 block will weigh slightly more than a 390 because the main caps are heavier and there are cross bolts. I think the difference between a 390 and 427 block is approximately 10 pounds. There is a difference in 427's, the irrigation blocks were intentionally made with thinner cylinder walls for better cooling so those are going to be somewhat lighter.
Hey if you want to see a heavy 427 block try the new Genesis iron 427 reproduction block. I just bought one and weighed it at 233 pounds!
