OEM Mopar Engine Weights
Here's a small list of [approximate] weights for stock engines.
Note most of these are fully dressed engines with stock parts.
We all know the savings to be had with aluminum intakes, ect...
331/354 Hemi with alum. intake and water pump - 504
392 Hemi with alum. intake and water pump ------ 564
Slant 6 --------------------------------------------- 525
273-340 ------------------------------------------- 525
360------------------------------------------------- 560
361-400 ------------------------------------------- 620
413-440 ------------------------------------------- 670
426 Street Hemi ----------------------------------- 765
I'd seen this chart before and I find it hard to believe it's accurate. When I put my 331 on my one engine stand it looked like it couldn't handle the weight. (I couldn't keep it from sagging) The same stand with our 400 (512 stroker) on it was no problem. Both engines fully dressed. I never weighed either but it really, REALLY seemed like that Hemi was a good amount heavier. I found a different list of Mopar engine weights on http://www.dippy.org/forum2/index.php?topic=1474.0

The only engine shown that's more than 200 pounds different is the slant 6, but it does show those old Hemis to be pretty heavy nonetheless. I don't know if their list is accurate either.
