Techie Question......Jaguar V8 engine !!
Discussion
The Jaguar V8 engine as fitted to XK8, XJ8 & S-Types was designed entirely in-house at Jaguar's Whitley facility in Coventry.
The engines are manufactured in the Ford Bridgend facility.
They have nothing in common with any Ford or Rover V8.
There is a Ford built variant of this engine that was fitted to Lincoln LS and Ford Thunderbird, it shared many parts and design attributes with the Bridgend built Jaguar engine, but was manufactured in Lima, Ohio USA.

Cant say I know the weights of either engine off hand but I have had both sitting next to each other and I would say the jag is definately heavier but not by a large amount and just as a matter of curiosity the only part ford supplied for the AJ V8 was the sump plug apart from that they had no input!

Ford are masters of production engineering and had a huge input on designing for manufacture and manufacturing tooling of the engine. I think it was a statement made to appease the unknowledgeable and prejudiced rather than giving appropriate respect to all the contributors, including the ones who paid for the project.
The V8 fitted to very recent MG ZT and Rover 75 V8 models was a Ford unit, but the ubiquitous Rover V8 which powered everything from TVR to Land Rover was originally a Buick - and differs from the Jaguar engine in that it has 2 valves per cylinder and is an overhead valve design. The Jag unit has 4 valves per cylinder and is overhead cam. They are like chalk and cheese. Hope this helps.
Check my post in this link- it gives a total brek down of the RV8 engine weight.

The AJV8 originally in Nicasil form and comparing a similar baseline to the RV8 I quoted was 210 Kgs, however the type with nicasil liners is closer to 216kgs. So there's not much in it.
Bear in mind however that the Jag V8 has a much bulkier top end, with quad cams, chain drive, Unisea VCT units etc etc but the Rover V8 has a longer cylinder to cylinder distance
