Really! My 4.530 mega block weighs 330 pounds. The indy block weighs 130 pounds. a stock block weighs 230 pounds.

Sooo my Indy block is 200 pounds lighter than a mega block. And probably about the same for this new muscle motors block....


Wow, what version of megablock is it? This 230 pounder was an early mopar mega block that was furnished with a 4.19 ruff bore, then finish bored to 4.5. I have a mega in storage that I'm going to dig out and weigh.
