    Hello Rick,

    Thank you very much for taking the trouble of tracking down the book's new owner and grabbing the title, author, publisher and ISBN details. I greatly appreciate it.

    I tracked it down on Amazon with the matching details.

    Kind regards
    Lionel

    Hello All,

    One round trip of 994 kilometres broken up with an overnight stay later and I have a Range Rover 3.5 litre V8 with an LT95 gearbox attached sitting at home.

    I just received a notification from eBay that I was the winning bidder on a copy of the Tune Rover V8 engine book that Rick described. It is apparently in "near new" condition and less than half the price that other retailers were selling it for.

    After a bit of degreaser and some scrubbing I found the engine number. Next step is to match the engine number against the year of manufacture and the model so I can identify the correct parts catalogues and workshop manuals.

    The next step is to identify what the cut off wires are and where they are meant to connect to!

    Kind regards
    Lionel

    Try these colour codes Lionel.

    Lucas wire colour codes for Land Rover

    They didn't change for decades. I used them to completely rewire the engine bay in my pos with wire from a complete 1981 ish RRC loom.

    I just did it like that so all the wires were original colour and gauge.

    The insulation on my 1974 wire was only really degraded from heat in the engine bay. If you can get hold of a whole loom from a similar vehicle you're going to put this 3.5 into you'll have plenty to work with and it'll be the correct colour and gauge for purpose.

    I soldered all the joints 20 + years ago and have had zero problems.

    cheers, DL

    Hello All,

    I bought the V8 Rover Tuning books when I thought the engine was described in the advertisement - a 3.5 litre V8. After I got the engine home I found the engine number and searched online. I found out that the engine was a Rover motor that was fitted to a Morgan Plus 8 and it was a 3.9 litre motor. How much of the content of the V8 Rover tuning books for the 3.5 litre transfer across and be pertinent for the 3.9 litre motor?

    A number of people have assured me that I am better off with the 3.9 litre motor. Apart from the extra 400 ml capacity what are the benefits of the 3.9 litre motor over the original 3.5 litre version?

    Kind regards
    Lionel

    Hello Loan Rangie,

    Well that is not too bad then. Just have to work out the 5 percent that does not apply to my engine. Hmmm.... I wonder what 5 percent that is though? Tee-hee!

    Kind regards

    Cam, carburation and compression I'd suggest, Lionel.

    Hello Ian,

    Just done a bit more digging and I found a 3.5 litre to 3.9 litre V8 conversion kit from Rimmer Brothers. The kit contains surprisingly little conversion... As they describe ...

    Re-sleeve the block using the liners supplied and fit 3.9 litre pistons. The existing 3.5 litre crank is retained.
    Kit includes all components listed in Full and Short Engine Rebuild Kits, plus a set of 8 standard size, 3.9 litre, 9.35:1CR pistons and cylinder liners. (Accessed 22nd May 2023 from, Rover V8 3.5 to 3.9 Conversion Rebuild Kits | Rimmer Bros). My engine is already a 3.9 litre so it does not need the kit. Still very interesting how little needs to be changed.

    Kind regards
    Lionel

    Hello All,

    At last I think I may be able to date what year my Rover V8 3.9 Litre was made in! The engine number is 47A07767B This is identified by the V8 Forum as:

    Factory 3.9 Litre Engines
    47A00001 Morgan +8 9.35:1 CR EFI
    Accessed 4th of October 2022 from Rover V8 Engine Numbers (Rover V8 Engine Numbers)

    While this and other websites identify the engine number as belonging to a Morgan Plus 8, they fail to state when the 3.9 litre motors replaced the previous 3.5 litre motors fitted in Morgans. Tonight I found a Wikipedia article that suggests that, "In 1990 a 3.9 L version of the engine was fitted and that used the Lucas 14CUX fuel injection system. All Rover/LR Plus 8 versions between 1976 (Sd1) and GEMS are very easy to upgrade to much greater power" (accessed 22nd of May 2023 from, Morgan Plus 8 - Wikipedia). Okay, so Wikipedia may not be renown for being the most reliable of sources. However, it is the best information that I have to date. I did contact the Morgan head office and exchanged emails with them. If I wanted to pinpoint what exact Morgan Plus 8 that engine number was fitted to and when the engine or car was made, I would have to pay them 180 UK Pounds for the privilege. Umm - I think I will stick with Wikipedia thank you!

    So, my engine may have been manufactured from 1990.

    Further validation that the engine may have been fitted to a Morgan Plus 8 is provided by Rover V8 Engine Numbers However, they too like the Rover V8 Engine Numbers site, fail to provide a year of manufacture.

    Kind regards
    Lionel

    Lionel, not all 3.9s are born equal.
    Even Land Rover offered high and low compression versions.
    Quite possibly Morgan offered an even higher compression version. Easily done with different pistons (most likely) and/or shaving the head.
    A more aggressive cam grind will also produce more power.
    If you don't like trucks, stop buying stuff.
