weirdest engine

A friend and I are actually looking at a Ford Super Duty 534 gas engine. They were made from the 60s all the way through the 80s. In fire trucks and the like. The engine with bare necessities like just the alternator and belts weighs right at 1000 pounds. But could you imagine what that would do in a light rat rod? Not to mention how different it would be. It looks like no other Ford engine at all.

Here is the beast. Just for size reference, I know yall recognize the Carter AFB on top. LOL
