Extra Weight of V-8?

[Spuds]

Anybody know how much additional weight the 5.3L has over the 3.7L?

[H3slate]

H3 Alpha 4,851 lbs
H3 4,700 lbs

This is according to the Hummer website.

I think the H3 Alpha also has a cast iron front diff, and more stuff inside. The engine itself might be 75 to 100 lbs more.
