360 heavier then 318?

as you all know the 360 in my duster is finally alive!!

but.... my headers are almost touching the ground. car sits a good 3 inches lower in the front. is the 360 heavier?

or because it had no weight in the front for 2 months the torsion bars got weak?

i reckon the 360 is a bit heavier but not that much as to pretty much touch the ground

wondering if anyone else has seen this :burnout::burnout:
