engine identification
HI all another newbie to the forum.
Having looked through the engine number listings my 3.5 engine number 47A35P.
appears to be a TVR number or maybe a Morgan number !ALL TVR and morgan 3.5 v8s run the 9.75 compression ratio i think so iam confused because 9.35cr is stamped next to the engine number????????????
Any thoughts on what it might be .
cheers kev.....

4.6 Service Exchange
Just taken delivery of a second-hand short engine which at first appeared to have no identification or engine number, but after cleaning up I found a neat little plate riveted to the front nearside block face:
Land Rover Parts Ltd. Service Exchange
Model: STC 1967 E
Serial No: AAA S16861 E JO
There is also a number cast into the block: HRC 2411
The bore and stroke check out as a 4.6 (94 x 83), so I'm happy I've got what I paid for, but can anyone say what vehicle, CR, or date this engine might be?
Thanks

P6 engine in a Land Rover - possible to tie down the year?
V8 fitted in a series 3 Land Rover and the log book points to it being an SD1 engine (states 10A......) but now found the engine number at the back of the block and it is 42523546C so its actually a P6 auto block from 1967-76 but is there any way of getting closer to the year of manufacture?

425 engines are RHD UK auto cars.
Numbers on the back of the block are earlier engines, and are suffix "A".
"C" suffix is later so should be stamped on the top of the block by the dipstick.
Both are 10.5:1 cr, but the "A" suffix has a rope rear main seal, and the "C" suffix should have a lipseal rear main seal.
"C" suffix would be from about 1972-4.
Re: P6 engine in a Land Rover - possible to tie down the yea
Thanks. The number is on back of the block (the bulkhead side) not by the dipstick, which is why I couldn't find it as that's where I had been looking. Wasn't until the gearbox was out at the garage was all revealed. Just rembered the old distributor was swapped earlier this week and I still have the old one in the car. Just checked and it has 35DB and 46 71 stamped in the body so this must relate to the week and year of the distributor?? If so its likely a very late 71 or early 72 engine I guess.harvey wrote:FFG wrote: but now found the engine number at the back of the block and it is 42523546C so its actually a P6 auto block from 1967-76 but is there any way of getting closer to the year of manufacture?

Just been looking at the area adjacent to the dipstick. It has 47AnnnnnA (where n is a numeric character) which would indicate Morgan +8, but also has 47A40PnnnG above this in smaller text which would indicate TVR Chimaera. Perhaps an attempt to make the engine look more valuable?
Any ideasuggestions what this may be?

Re: Rover V8 Engine Numbers Updated:
Hello,
I have a 1989 Land Rover Defender with engine 24G05055B, but the information I have from the British Motor Industry said it was built with engine 24G05055C. Is it possible there was a typo somewhere? Is there another stamp somewhere that I could verify?
Thanks,
Jared

Re: Rover V8 Engine Numbers Updated:
Hi all, mines 36D01493A, so its a 3.9 efi auto out of a Disco '88 on. Anyway of knowing what actual year it is and would it be a 4 bolt main engine? Not taken the sump off yet.....
Re: Rover V8 Engine Numbers Updated:
Only the 4.0 and 4.6 (and their variations) had 4 bolt mains.
The 3.9 with its smaller crankshaft has the pads cast into the block for the cross bolts but were not drilled for them and the bearing caps were not drilled either.
Also your engine was most likely out of a RR (88 on) as the Discos did not get the 3.9 until much later and your engine is an early number. Also it is a Hi Comp engine which is a bonus.

Re: Rover V8 Engine Numbers Updated:
Hi could any one help me with my engine number for the year of manufacture as my kit car will require a IVA test when finished the number is 23D08345D cr8.13.1 and is there an easy way to find out if this is the CR with out taking of the heads off as the engine has been rebuilt thanks Keith
Re: Rover V8 Engine Numbers Updated:
That engine number comes up as 23Dxxxxx = 1990 Landrover Discovery Auto EFI - with CR 8.13:1
So when originally built it had a compression ratio of 8.13:1
