Standard Rover camshafts SD1 v's Rangie ?

[badger]

Cool, it's nice to hear some feedback - I never seem to get much. I reckon it's down to the simple fact that most folk aren't interested in making further contact unless they have any problems. A very nice wee 90 that one, obviously well looked after, one of the cleanest engines (internally) that I've seen in a long, long time. pass on my regards when you next see him, cheers.

RP4 cam is a Piper cam as are all the RPI cams including the tourque max. You can get a kit for the webber to make it more off roadable. No idea what it is but some of the guys on here use it to good effect. One thing I would suggest is only change one thing at a time. If you go changing too much at once you might get to where you want but cost you too much money or you could easy end up somewhere you definitely don't want to be. Another option could also be choose whatever can you think is best and also use a set of Rhoads lifters. They leak down at low revs increasing the torque. Generally used on lumpy cams to tame them a bit but no reason you cant use them to good effect on a smaller cam to give that extra torque monster effect. They do clatter a little on idle mind you but its a small price to pay.

With regard to the Rhoads lifters, I'm looking for new lifters on a standard 3.9 cam, would they make much difference or am i better off sticking to a standard lifter.

I once fitted Rhoads lifters and removed them after 3 months when I got fed up with people asking me if I had fitted a diesel engine to the car.
Naturally, I had to replace the cam as well, so be sure before you buy.

I don't think you would see any advantage with them, they only give you full lift above about 3500-3700 revs, a standaard cam would normally give you peak torque at about 3000 to 3500 so you will be reducing peak torque (as you will reduce valve lift and there for volumetric efficiency). They are only an advantage where peak torque comes in above where these lifters give you full valve lift.

Cheers guys for the replies its great to get a second opinion.

I'm going with standard lifters, prices vary from 1.95 each to 7.10 each, thought about V8 Tuner, where i got my cam from, otherwise back down to the LR stealers.

running rhoads in mine and aint that noisey at all.
was expecting worse the way people have said how noisey they are.

I suspect that oil pressure plays a part in the bleed down and recharge rate of the Rhoads lifters and consequently the resulting noise level.
Thinking back, mine were fitted to an engine with an early P6 oil pump with low hot oil pressure at idle. Higher oil pressure from later pumps would probably reduce noise from the Rhoads due to faster recharge.

We have gone through several sets of Rhoades in the dragster with no problems at all. Could not comment on the noise as open headers stop you hearing anything else. Performance wise they do what it says on the box. We could run the hairiest cam available and still idle below 1000 rpm. However for a stock cam I can see no benefit whatsoever. Go with good stock lifters. No-one seems to mention Real Steel for parts but we have had nothing but good experience with them. We once had a faulty race cam, they replaced it and even provided a full cam checker print out for the replacement. Might cost a little more but our experience of the service they provide gets them an A1 grade.

"Might cost a little more"
Not my experiance, short of importing it yourself they are often the cheepest (bearing in mind they don't generally fob you off with cheep parts but get you the real thing) that is for chevy and US aftermarket bits especially. A few times I have bought stuff from them because they are the cheepest source (for some reason chevy solid roller tappets when I last looked ).
The issue is, though, they generally only sell good parts so you see it reflected in the price. A friend of mine used to say the price of oats should reflect weather or not it has already passed through the horse
Famous four also used to be very good on RR Bits.

I switched to Rhoads a few years back and won't run anything else. My suggestion is that you look into the Rhoads V-Max which allow you to adjust the bleed down rate to your cam size and reduce or eliminate the "ticking" completely.
