The initial Rover version of the engine had a displacement of {{cvt|3528|cc|L CID|1|order=flip}}.<ref>{{cite web |title=50 years of the Rover V8 |url=https://www.autocar.co.uk/slideshow/50-years-rover-v8 |date=29 January 2018 |website=Autocar |publisher=Haymarket Media Group Ltd |access-date=8 January 2022}}</ref><ref>{{cite web |last1=Adams |first1=Keith |title=Engines: Rover V8 |url=https://www.aronline.co.uk/engines/engines-rover-v8/ |date=15 October 2017 |website=AR Online |access-date=8 January 2022}}</ref> The bore and the stroke was {{convert|88.9x71.12|mm|in|2|abbr=on}}. All Rover V8s were OHV pushrod engines with two valves per cylinder. It used a sand-cast block with pressed-in [[iron]] [[cylinder liner]]s, and a new [[intake manifold]] with two HS6 type [[SU Carburettor]]s. The Rover engine was heavier but stronger than the Buick engine, with a dry weight of about {{convert|170|kg|lb||abbr=on}}. It was first offered in the 1967 [[Rover P5#P5B|Rover P5B]] saloon, initially making {{convert|184|PS|kW hp|0|abbr=on}} (gross) / {{convert|160|PS|kW hp|0|abbr=on}} (net) at 5,200&nbsp;rpm and {{convert|226|lbft|Nm|0|abbr=on}} (gross) / {{convert|210|lbft|Nm|0|abbr=on}} (net) of torque at 2,600&nbsp;rpm on 10.5:1 compression (5-star petrol was then still available in the UK). With the introduction of the Rover SD1 in 1976, the engine was improved with the 'rope' oil seals for the crankshaft ends replaced with lip seals, spark plug dimensions changed and the compression ratio lowered to 9.35:1.

===Project Iceberg===

In the late 1970s, British Leyland became aware of the increasing importance of [[diesel engine]]d cars to the British, European and (especially) North American markets in the wake of the [[1979 energy crisis]]. It was decided that a new series of diesel engines powerful, refined and economical enough for use in BL cars was needed. However, with development funding tight, it was necessary to use existing BL petrol engines as a base. This included a diesel version of the {{convert|3528|cc|L|1|order=flip}} V8, the development project for which was code-named 'Iceberg'.<ref>{{Cite magazine|last=Saville|first=Mark|date=Spring 2004|title=Rover V8 - Gone but not forgotten|magazine=Land Rover Owner|page=55}}</ref>

BL collaborated with [[Perkins Engines]] of [[Peterborough]] to develop the engine. Both [[naturally aspirated]] and [[turbocharged]] versions were produced, both using a [[Stanadyne]] rotary [[mechanical fuel injection]] system. Power outputs of around 100 (naturally aspirated) and 150 (turbocharged) horsepower were achieved.

The Iceberg engine was slated for fitment in the [[Range Rover]], [[Rover SD1]] and the [[Jaguar XJ]] but the project encountered problems with failure of the alloy [[cylinder head]]s and internal cooling. They were limited by the need to use the same basic block casting as the petrol engine to allow the Iceberg engine to be produced on the same production line to reduce costs. Whilst these problems could have been overcome, the project ran into financial and logistical problems caused by the reorganisation of BL and specifically the splitting of [[Land Rover]] and [[Rover Company|Rover]] into separate divisions.

Land Rover took over production of the V8 engine in 1982, moving it from the main BL engine plant at Acock's Green into a new, much lower-capacity production line in the [[Solihull]] works, where it was built alongside the other [[Land Rover engines]]. This meant that there was no spare capacity to build diesel versions of the engine. Coupled to this, it was clear that the market for large diesel engined cars in North America had not developed as expected.

BL finally pulled out of the project in 1983. Perkins initially decided to pursue the project alone, and even produced advertising brochures for the engine as an industrial power unit, but BL withdrew all technical support and Project Iceberg was wrapped up in late 1983. BL's other collaboration with Perkins (producing a diesel version of the [[BL O-Series engine|O-Series engine]]) produced the highly successful 'Prima' unit. BL (and its [[Rover Group]] successor) bought in 2.5-litre 4-cylinder [[turbodiesel]] units from [[VM Motori]] to use in the SD1 and Range Rover.
