Hi I'm just curious and will probably ask the seller later but I've bombarded him with lots of questions already, so will wait a bit.
My car has a SD1 3.5 11A SD1 auto 9.35:1cr 1976-1987, but it's actually running a Manual LT77 gearbox, installed.
It's just broken, no compression on one cylinder and it was pretty tired anyway.
So I've bought a refurbed unit which is described as a 3.9. taken out of a TVR. I asked if it will accept all the SD1 bits and was told yes.
I asked for the engine number as was told 37A which I looked up and is (TVR 350i 9.75:1cr efi) is it likely that part of the refurb is that it's bored out to 3.9 or did they make 37A engines in this size?

I’m not a TVR expert but I did have the tvr 350i wedge shaped tvr which indeed was a 3.5 engine which was superseded by the 390i which is the 3.9. I guess if you ask in the tvr section you would get more info

Amazing how many Rover V8 engines were 'taken out of a TVR' without any provenance. I wouldn't even trust the capacity was as stated, let alone where it came from.

Thanks for the replies, It looks like it is a Chim 3.9 as the engine number is 37A40P.

Any those TVR engines are largely bone stock too.

Being the sceptical chap that I am, the refurb could've been a proper one where they've re-bored it and fitted new pistons and rings. They've might've just cleaned it and painted it.

I've got a 3.9 from a Range Rover (36D engine number) which I'm re-building. It's been re-bored and is about to be put back together.
