about going efi on my 3.5 or swapping out for a larger efi unit?

I appreciate that I may get jumped on for this but I'd be happier with efi under my bonnet than the existing edelbrock and 390 combo. There is nothing wrong with the engine (It's been well looked after and has sd1 heads, mallory distributor etc) but it would also be an excuse to enlarge engine size if engine bay/bonnet clearance will allow.

I actually have access to a ford 5.0 efi but it would be nice to keep the powerplant in the family, so to speak.

Just curious is all at this point but it is something that I could start assembling/hunting out parts for.
 
EFi and the P6 have history. The 4 pot 2000 was intended to be launched with EFi in '68!! And the 3500EI should have entered production in October '70. A full maintenance manual from the 4 pot survives in captivity.

So nothing out of the ordinary about an injected V8 in the P6. All the ex Range Rover and TVR engines bolt straight in given that you fit a P6 or SD1 front cover - the later Range Rover "serpentine" front cover is too long for the engine bay. Nor, I understand, is there any height problem fitting the plenum under the P6 bonnet line. Most people seem to use a Range Rover loom and ECU etc, but others have used proprietory ECU's (Have a look at BBLongman's posts).

Duly noted.

Why oh why didn't they go ahead and do it?! :shock:

Any idea on which year the later serpentine engines started? Or is it really as simple as finding a 3.5 efi setup where the engine is concerned? (Seen a few listings on the 'bay).

Cheers :D
 
Hello JIMMY,

Serpentine refers to the drive belt system used to run all the ancillaries including the water pump. Such a system began in 1994 with the introduction of the "interim" 3.9 and 4.2 litre engines. The same system was also used on the 4.0 and 4.6 litre engines, and in all cases the water pumps rotate in the opposite direction to all non serpentine Rover V8 engines.

The confines of the P6 engine bay mean as Chris indicated only P6 or SD1 timing covers can be used, which also means retaining P6 water pumps as the SD1 pump has a far longer nose meaning fan / radiator clearance issues.

Ron.
