V6 vs V8 engine weights

[maddog]

Hi guys, I'm wondering if anyone might know this information of the top of their head, or be able to easily get it.

Need the weight of the following: (engine only, not incl. transmission)

Holden 3.8 out of VP
Holden 3.8 out of VS/VT (ecotech)
Holden 5.0
Holden 5.7

Your info is greatly appreicated.

Well i can tell you that the Ecotec 3.8L weighs 12kg less than the 3800 in the VP... But I dont know the actual weights, sorry dude.

LS1 weighs in the 200kg mark

I can also tell you that the 5.0L is heavier than the LS1 by about 30kg but i dont know the exact weight difference....It was 30 something kilo's anyway...perhaps 33kg? *shrugs* will try to find the direct quote

Theres sites around that state the advantages of the newer engines...but they only say how much lighter the engine is than previous rather than giving actual weights?

Heres the quote for the Ecotec to the Buick anyway:
"Although the stroke for the 3.8 L engine remained at 3.4 in (86 mm), and the bore remained at 3.8 in (97 mm), the engine architecture was vastly changed. The piston connecting rods were 1 in (25 mm) shorter, so the crankshaft was redesigned. A new intake manifold improved breathing, and a new cylinder head had larger valves. The result was 147 kW (198 hp) and 304NM, better fuel economy, and 12kg (26 lb) lighter overall weight."
