Cam

[drewclare25]

anybody here put a new cam in a disco??

how much of a pain is it? i heard it can be done wihout taking the motor out.

and how hard is it to get the timing right after you put it in, simple as any vehicle with a timing light? i know rovers are usually more difficult thats why i'm asking.
i'm looking at putting a cam from a 4.6 into my 4.0 i know it will fit, but does anybody have any idea how much power i'd gain?

Don't waist your time with a factory 4.6 cam, you won't really see any difference.
There are good aftermarket cams that can make some great low end torques and power. If you can't find them, talk to Tony at LRR forum, he is the owner and also has a great repair shop. They install cams in quite often, You will need new lifters, timing chain and gears, upper gasket set plus hoses and all the fun little parts that broken along the way. Depending on your mileage, check out the rocker assembly for wear while you are in there. Before you start, consider doing a really good engine flush to get rid of as much crap as you can before opening it uo.
And yes, it can be done in the truck and is pretty straight forward.

Drew, timing a cam has nothing to do with a timing light, the timing light is used to set the Ignition timing.
To time your camshaft you will need to know where the timing marks are on the crankshaft timing chain sprocket (small one at the bottom) and on the Camshaft sprocket (big one at the top) and what position they need to be in to sychronise the valves in the head with the position of the pistons. You will need a Workshop Manual for your model or similar, which will show you the orientation of the sprockets when number 1 piston is at Top Dead Centre (TDC). Some aftermarket camshafts come with indexed keyways in the crankshaft sprocket so as you can Advance or Retard the Cam timing in relation to the crankshaft timing, usually these Cams come with full instructions, once you have the Camshaft timed to the crankshaft you can then set the ignition timing with a timing light, refer to your W/shop manual on how to replace the Distributor so when the #1 piston is at TDC when you slide the Dist. in the rotor button should be pointing to #1 on the Dissy cap.
I know I have written this rather simply as I don't know how much knowledge you have in this matter, I hope I haven't offended you, if you know more than I thought, because of your statement about the Timing Light, good luck, Regards Frank.

You do not want to put a torquey cam in an auto. The auto provides enough low down torque. The cams that are standard in the motor are designed to pass anti-pollution requirements and sacrifice a little power to do so. You will notice a little increase in power from a new cam, if you get the power curve in the right spot.

Ian, did you ask your mate in Adelaide if he has any Fairey O/D parts, I now need the mainshaft as well, would appreciate any help, Regards Frank.

I just installed a custom crower cam in my 4.6 (99 D2).

I got the entire kit from Mark at D&D (aluminumv8.com).

I have a distributorless motor which uses a cam position sensor and crank position sensor for timing.

The kit included the cam, lifters, timing chain and sprockets (upper sprocket modified with reluctor plate for cam sensor) as well as the spacer needed to space the cam sensor back a bit.

Great low end torque.

He makes this setup for Bosch as well as GEMS applications.

It may be alot less for your application as you would not need those extra bits if you have a distributor. Mark will be able to tell you what you need.

I put mine in while rebuilding my engine, but I understand that it can be done while in the vehicle. The radiator and AC condensor will have to be removed for access, but I have read that someone was able to just unbolt the condensor and tie it out of the way, so the lines would not have to be disconnected (requiring a recharge of refrigerant).

Mark was also able to supply me with all the gaskets I needed except the one for the upper air intake (D2 only I think).

I think the whole kit was $450 plus gaskets.

His prices are pretty good.

got a crowler set up in a gems allso from d&d did it about three years ago will never go back to stock
