rear mount turbo would probably be easier haha but there goes any water fording ability, daily driver n snow no prob though haha

 

Sorry to thread jack, but I have a question about a cam for a 4.0 rover?

I want more power from my discovery 1, I already have a straight pipe exhaust, headers, cold air intake, and some head work done.

I figured the best place to go from here is a cam, but its very difficult to find any for the 4.0 specifically, and cheap.

However there are cheap kent cams aplenty advertising for the 3.5 in old discovery's and all the way back to the sd1.

Will these 3.5 cams fit in the 4.0?
Thanks

The 3.5 engine was carburetor fueling hence the duration was longer to develop a deeper vacuum for their useage.

Fuel injected engines such as the 4,00 litre use a different duration and overlap to achieve power.

You need to to consult a cam specialist perhaps one used to the forerunner of the engine when it was known as the Buick 216 and its later derivatives.

The cam is available in blanks and can be ground to suit various applications and the only difference is the nose extension for distributor oil pump drives. Which of course can be parted off and a machine threaded stub cut to accept the drive sprocket fixture.

Thank you so much for the informative post, I didn't know the grinds were different for the different fuel delivery systems. I think I may just go with the MC2 Cam from V8 Developments. It's pricey but I think it'll be worth it

Thanks!

 

what year di? does it have a distributor?

 

It's a 97 D1, around 100k miles on the odometer. Gems engine management. So, no distributor. Coil packs around the back. From what I've heard that is a little more reliable than the distributor.

I've got a cold air intake, decatted exhaust, and a cam with worn lobes.
I think the worn out cam takes away any power gains from exhaust..

 

Contact the people at D&D in Michigan. These Rover engines are their specialty. There are Crower Cams you can use, Kent Cams and others, all set to achieve different performance ends.
