Engine identification

I have just joined the forum as I have recently bought a 1968 Mk 2 Cortina with a Rover V8 engine. I am trying to identify it to save time when buying bits and faced with question 'what car is it for'.

Engine number on side is 451113000 (could be a D) above that. It has 925:1 CR above it which I assume is the compression ratio. However another site says that range of numbers has a 10.5 :1 ratio.

Also number on drivers side cylinder head. ERC 0216X and below that is 3 E652.

Destributor has no obvious marks such as make but has a black top. carb is a mighty Edelbrock.

lots of things can change with the suffix (the D) the info I have says it should be a P6 engine with 10.5:1 but that's suffix A. This matches what Rimmer Bros have as well.

Thanks for that. It is the 925 reference that is confusing. I am aware there were some low compression engines made for the Range Rover.

I think the main thing is for parts its almost certainly a P6 engine. Most of the parts are interchangeable between 3.5 engines anyway so you probably cant go far wrong. some exceptions between P6 and later engines being seals for example.

You're not alone in having one of those - It's a late model P6 Rover - the last of the lines were 9.25's

The heads however sound like later SD1 heads
