Thread: Are all Landrove/Rangerover V8 Blocks the same?

Pretty much, when they moved to the serpentine belt (3.9) the crank snout changed due to the oil pump but otherwise much the same - all 3.5's are basically the same.

In general 3.5 and 3.9 blocks are the same - some later blocks have extra webbing. 4.0 and 4.6 blocks, while similar to 3.5/3.9s have some differences such as larger journals in the crank and four bolt mains. As i understand it timing covers can mix and match but some may need a little modification.

Thanks guys thats what I thought just wanted to confirm

If your 93 block doesn't take the serpintine belt it will bolt straight on.

There were lots of small changes done over the years, but like most things land rover bits will bolt onto other bits.

There's heaps of info if you look up 'how to power tune a rover v8' - you can read it on Google books.

Been after that book for a while, its out of print and i cant find an E-Book download either

Just remember that all Rover V8 blocks are BACKWARD compatable, IE you can fit all older hang ons to a newer block.

BUT not necessrily Vice versa, as the engineers didn't have their crystal balls working very well in the 70s and 80's.
Eg you cannot fit a crank oil pump timing case to a block /crank with a short nose .

Not quite true unless you mean the P38/D2 oil pump/timing cover assembly, although I reckon you could get away with it with the 10mm less nose length in the front pulley. I fitted a D1 serpentine front cover to a vee belt 3.9, just had to recut the keyway in the crank to suit the longer key. I wouldn't recommend it for the faint hearted though...but then you could just swap the crank.

What I find interesting is how LR kept the pickup oil gallery in the 4.0/4.6 block even though the new front cover design uses a totally separate pickup. This is why you can fit one to an earlier set of accessories.

Ok, so whats the consensus here, do I carry on with this 3.5 block I have which has had a 20 thou bore already and the crank has been done cause the bearings are marked +10 thought, I pulled the pistons they look good, so do I bother sending it to be checked out honed and tidied up or scrap it and source a 4.6 short motor from somewhere, it will eventuallybe going in my pre update D1
