Rover V8 Dimensions are often misquoted on the web. The weights given are often on the light side too. The dimensions suggest an engine with exhausts, fans and torque converters. The weights however suggest a completely stripped engine without inlet manifold, exhausts ancillaries etc. A running unit, with oil and water, would weigh another 50% over the 230lbs often quoted.
Either this engine has shrunk with age or the figures are simply wrong or misleading.
There has been a dimensional drawing of the Rover V8 kicking around the web for years. The drawing looks to be of an old P6 Rover V8 with some form of single carburettor. The drawing doesn’t show exhausts but the width suggests their presence.
The drawing below is what I’ve found on the web and as you can see, I think some of the claimed dimensions need adjusting or further clarification.
I know that the Rover V8 dimensions claimed might include exhaust headers, viscous fan assemblies, su carbs etc, but from my measurements, I came up with completely different results.
The engine shown is 762mm wide, so I assume their dimension must include old cast iron P5 or P6 exhaust manifolds or a overhanging alternator.
The old drawing claims the engine to be 843mm long and 711mm tall. So I can only assume that they were of an old 1960’s /1970’s P5 or P6 Rover V8 with some kind of carburettor, a huge plastic fan assembly on the front, flywheel and clutch (or torque converter) on the rear. they just didn’t bother to depicted on the ‘sketch’.
For modern Range Rover P38 engines, installations with electric fans, shorter pumps, no distributor, direct drive oil pumps, fuel injection etc, this old drawing is completely useless.
Sorry, I’ve not draw up the block or heads yet
To clarify, these dimensions are for a Rover 3.5 V8 Vitesse EFi, that has been converted to use the shorter Serpentine water pump.
Although I have taken every effort to make sure these Rover V8 dimensions are correct, measuring such a bulky item with digital micrometres, height gauges and squares is not easy! So take these dimensions as ‘good but not perfect’. Realistically, that is all that is needed, as nothing replaces trying to fit the real engine into it’s intended hole.
So, I’ve pretty much rubbished what I’ve researched from other websites, but as my previous blog articles will prove having the dimensions of an engine will only get you so far. Lets face it, an engine isn’t a perfect cube and some bit of it will desperately try to occupy the same space as another vital component such as steering or brakes. Fitting an engine will no doubt require some component to be ‘adjusted’.
The Rover V8 CAD has been slow – mostly because I’ve been out in the workshop rebuilding the real thing.
