omg, yes, they are absurd....I removed the original one from this engine in ~1999 and its still in my shed somewhere...I have a nice edelbrock RPM on there now that I painted up too look as stock as possible. I always found it funny that my car with a 650+lb big block, cast iron 4 speed trans, cast iron bellhousing, cast iron flywheel, 9in ford rearend that could anchor a ship....still like 700-800lbs lighter than a modern mustang/camaro.
I stripped it all down before putting it in the car, but here's the motor all put together on the stand..
