No problems there.
>From the P6 engine you need:
sump and strainer,
you need an electric fuel pump
cause the SD1 timingcover has no
provision for a mechanical pump.
if using the SU carbs try a pump with
no more than 3 psi, else use a pressure regulator.
Principally the SD1 timing cover is better
as it has a better oilpump.
the SD1 engine also use a different oilfilter
Now I think that is all.
The CR of the P6 engine is 10,5 : 1 and
the SD1 9,35 : 1.
If possible use the 5-speed box too.
Regards and good luck,
Lex van Opstal.

Onderwerp: [ROVERNET - UK] '80 SD1 block into a '70 3500s
I'm rebuilding a seized '70 3500s engine, and considering using a block
(complete) from an '80 SD1. I understand the compression ratio is
different (9.xx:1 vs. 10:1 in the older engine), and I'm wondering if
there are any problems or special considerations I should be aware of
in making the exchange?
Thanks for any advice you can send my way.
