V8 Engine Weights
Discussion
Does anyone know the comparative weights of a Rover V8, Chevy LS* and Ford Modular, Winsor and Cleveland engines all in a similar state of build, preferably ready to run.
I’ve found a few sites such as this one www.241computers.com/ford/ContentExpress20-30-38.html but the data is from all different sources and there’s no guarantee it’s comparing apples with apples

Marquis Rex has posted the true weights of V8 engines on here before.
IIRC the Rover unit is no where near as light as some people think it is. It's actually rather heavy by todays standards in the smaller capacities.
It goes something like-
Rover 440lbs
LS1 460lbs
old small blocks 540lbs

Those figures aren't quite right imo. I accept that the rover is a lot heavier nowadays but the chevy is meant to be about 400 lbs. So, I'd guess the rover to be about 360 lbs. The chevy is certainly heavier then the rover and not something I like to lift to often. That said, being alloy it's still nice and light.

These are the true weights of a late Disco 4 litre engine, compliant with all the modern emissions and refinement criteria.
Accessory Drive Belt - (1) 0.341kg
Air Cleaner Body 0.977kg
Air Cleaner Element 0.299kg
Air Cleaner Top 0.467kg
Air Flow Meter 0.226kg
Air Hose/Duct - (1) 0.325kg
Alternator 7.196kg
Engine Complete 177.000kg
Engine Management - E.C.U. 0.390kg
Starter Motor 4.060kg
Viscous Coupling 2.942kg
Engine Oil 5.676kg
The above comes to 200 kgs. Now an earlier vehicle will probably NOT have the reduction gear starter motor fitted and so you can expect that to weigh about 8 kgs, the accessory drive won't be poly belt driven but individually driven So that will weigh quite a bit more. The above also does NOT include the flywheel, which on the Rover is very very heavy compared to it's contemporaries. So we're already looking at way over 220 Kgs. The extra capacity over the 3.5 litre will lose some in the crank area, but because the RV8 doesn't have a fully counterweighted crankshaft- not as much as you might imagine. The block has been reinforced since the early days, but I can't see that adding much more then about 5-6 kgs.

It's certainly getting heavy but the engine's complete at 177 kgs. It does make me wonder what the defination of complete actually is. If you were to transplant it into another car you would probably start binning stuff.
