Mystery Engine Number
Hi,
Been asked by a fella over on a TR7 forum I am on to help I.D a engine number for him, it is -
46A00708A
Its a late 3.9 / 3.5 block with cast crossbolts BUT not tapped, fitted with a SD1 type front cover, you can see that the engine number has been machine stamped into the block and has a compression ratio od 8.13:1 -
Any ideas ???
Cheers John

Maybe an export engine??
if you cant find the number on here try the V8 register or even give Rimmer Brothers a call

Yes it does. I was just thinking that maybe it meant it was of a similar age to a P38 engine (the style of the numbers looks to be the same). I would go with the theory that it is a special number sequence for a small sports car manufacturer, as pointed out above. It's a low number too, so clearly not a volume builder.john 215 wrote:Hi,
Sorry but looking at the picture it says 46A, I think ?
Looks unusual. I think 46D is the Range Rover P38 engine....
Cheers John

Could it be for a TVR turbo application?
Or is that too high a static compression fora turbo engine?

Could it be just a number for a spares new short block assembly - hence why no list as being associated with particular car.
There were quite a few of these new short assemblies kicking about a while back and may explain all the secondhand parts bolted to it. SD1 cover 14 bolt heads etc.
