I refuse to accept the fact that if I wish to buy a Rover part from a US vendor it must cost three times as much as the same part purchased from overseas!

I've been pricing cams. Genuine Rover cams in the US are about $300-in the UK, less than $100.

Good thing she's not in any hurry to get her truck back, but I'm wanting to put the Series away for the winter and get back into my warm/cozy Disco.

What's everybody running for camshafts? Performance/stock? I thought I had a CB lifter, but it didn't work out. Any suggestions?

Oh yeah, Autozone sux-they won't take a credit card over the phone to order parts? WTF? They want me to make two fawkin' trips?

Peace,

Paul,
I was under the impression that there were 'Merican camshafts that will work in our truck. Also I thought they were around $100 US. I know someone who has done this, just trying to remember exactly what he used.....

I'll think of it.

Paul
Id the one you want. I'll find a price
paypal me some funds
I'll collect and post a Gift to you save on import duty

OK, I found out some more info. Apparently there are several options depending on your engine.

The first is a Crane Cam (still trying to get the P/N) with a rev range of 1500-3500. This one is being used in a 3.9L and I think it is available from Summit Racing. Hopefully someone will cough up a P/N soon.

The second is a Rower 50227 Cam with a rev range of 0-3500. This one is being used in a 4.6L.

Probably best to phone Crane as there catalog doesn't do Rovers...

Probably best to call Crower. www.aluminumv8.com has 'em. A few around here have run the Crane cam for the Buick 215 (same cam) and were not especially thrilled with it. From what I recall, anyway.

a lot of folks install a new cam with a different profile, change nothing else in the engine to help the cam work, and then blame the cam :shaking:

In my case, a cam WITH a consistent profile would be enough to gain a major improvement. I didn't say anything about a different profile.

I measured my last camshaft this morning (after making a fixture to test them as the magnetic base kept falling off the lathe carriage :flipoff2: ).

I thought I had a good one 'til I go to the last four lobes and both #7 lobes were worn 0.050" And this was the best one :eek:.

Keep the suggestions coming, but let's focus on a stock (profile) cam (Cheap Bastard!).

that bites!

just out of curiosity, PT, do you think that these older motors would benefit much from port matching the lower intake? I've never had one apart to see what the tolerances are. I fear I'm going to have to pull the heads and cam on mine if these refurb injectors don't cure the emissions issues.

In my usual compulsive self, I have read much on these engines and the performance mods that have been done by others. The vast majority of what I've read indicates that working on the ports usually is only effective at the higher RPM ranges, something most of us (here at least) are less concerned about. Some of what I've read indicates that what would be considered to be a matter of course for a high-performance engine would have negative impact on horsepower generation at lower RPM ranges.

Given my observations, I'm beginning to think that wear on camshafts in these engines may well be responsible for the poor mileage and performance I encounter.

In the case of the 4.2 with the bad lobe, I'm now certain that the main/rod bearings adjacent to that lobe are probably gone and the lack of oil pressure (pissing out around the rod/crank) led to the localized wear.

With luck, I may have obtained another Range Rover to snag the engine from-but, the owner thinks it's worth far more than it is :flipoff2:

PT,
Just out of curiousity, how many LR's do you have around your shop? It seems like every time you need a part, you get a truck!

[PTS-voice] Honey? I'll be right back...your truck is missing a plastic rivit dohickey under the dash, so I'm picking up another parts rangie...ok? be back in a few days! [Pts-voice]


yeah! some of us wonder this at times too!

Paul(wishing I could do the same here....or do i? hmm! where would I put all those rangies...can hardly park one series and two coilers here w/o bitching from neighbors..finally down to only one othre rig(elisa's series III) sitting as her ex-husbands's mothers house until I can replace the frame I twanged!)

This sounds like a bit of story itself!

I've wanted to own a boneyard since I was a little boy. My wildest dreams really are coming true.

Off to make a deal on another Range Rover-and maybe another Disco too.

this is true for any engine if you're talking about increasing the size of the exh/intake ports in the heads - I was wondering specfically about what kind of overlap the lower plenum has with the intake ports on the heads.

I'd think that even port matching would potentially be delterious to our engines for low RPM activities. I'll take a look at the size of the mating ports to see just how far offset or occluded they are.
