What makes it so HEAVY?

[blacksheep06]

I understand the gt500 weighs over 3900 lbs but a 5spd GT coupe only weighs 3480. That's over 400 lbs difference, where's it all at?

I realize the 5.4 weighs more plus the SC and bigger brakes but what else is there?

That big old hunk of iron engine + the huge heads + the supercharger...

As srothfuss said, the engine is big and heavy.

The engine is responsible for 250 - 300 lb of the difference.
The iron 5.4 block +100 lb
huge 4V heads, 2 more cams, longer timing chains +70 to +80 lb
S/C & SC drive belts pullys, intercooler +80 to +100 lb
Heavier internals, longer rods, bigger crank, flywheel, bigger vibration damper +30 lb or so.

The 6 speed trannie adds weight.
larger radiator + the extra coolent the bigger heads & radiator hold
Bigger tires, wider wheels, bigger brakes,
the extra pounds add up very fast.

I didn't realize there was that much difference in the weight of the motor. Wow, all that hp comes at a price.
