Hi, can anyone help identify this Rover V8?
It doesn't seem to directly match up with the tables I've found online, so hoping there are some experts on here that can help!
I suspect it's not a factory stamp as it's all a bit wonky, but any help or advice would be appreciated...
Engine number: 45105681B

10.5:1 would identify it as an early lump from a P6 V8 forum =

I was starting to wonder if it was perhaps a 45100000A block that had been reworked or something... Not sure if it's common practice to restamp a block if it's remanufactured? Or if they typically reman old blocks in the first place?

No idea - but that stamping is correct for an old P6 lump - if its stock it will have a points dizzy, rope seals front and rear and short oil pump gears. May also have the small crankcase breather pipe at the back of the engine. Rocker covers off and you will have Birmal heads - probably double valve springs. Pulling apart further it will have small block webs. Does it have a flywheel or a flex plate - may indicate it being rehomed at some stage. ETA - or a spigot bearing in the crank.

Sounds like you might be heading in the right direction with your identification! It's got a flywheel on it, but they may have been swapped on at some point in its life.

Been rehomed as the LT77 is a good few years after that engine hit the streets.
The only bits I would keep are the flywheel, the LT77, rocker covers and the valve caps.
What are the numbers on the LT is it a V8 box? - short remote usually from a Sherpa.

I'll have a look and report back on the gearbox.
Are you saying these engines are only good for scrap then? Any insight into that?

Hi, Because of where the engine number is stamped it's a post '72 engine.

Not "only good for scrap", far from it if specifically wanting to run an early P6 motor. If wanting to run an RV8 there are better options that would not cost very much more overall. It depends what you are planning to do with it. It costs the same to rebuild an early P6, which is a somewhat weak design with rope seals, small valve heads, weak pistons, small capacity oil pump, as it does to rebuild a much later 3.9 that can be picked up for a few hundred notes. If it's a 3.5 you want to stick with then try and pick up a very late one - but with the 3.9 being much better engines with no drawbacks from the bigger capacity its one of those "why would you" things.
