Thread: What would you do?

I'd fix the originals.

How well do you really think it's going to go with a different carb on it? A different cam would be far more use.

As mentioned, you'll be stuck pretty quick on a steep hill with a standard Holley. There are plenty of people wrecking carbied 3.5's that still have good carbies of them. I'd be tempted to bung a set of second hand ones on and see if that fixes your issue. It's a lot of money to shell out on the Holley if there is another problem that is causing your issues.

1. If you want original and legal then stick with the carbies you've got. No Holley will pass a roadworthy inspection.
2. If you must fit a Holley they are a good combo with LPG. On their own they aren't really good on fuel.

3. If you want a cost effective performance upgrade, fit a hotwire EFI setup off a later model. You'll need the front end off a 91-93 RRC and the tank, pump wiring and fuel lines off an '86-89 RRC. Its almost a bolt in fit if you are handy with the tools. I did this to a carby 3.5 Defender for a fellow forumite and it was a great success. It should also be completely legal as it's off a later model.

I think you can. I took a cheap spanner and then bent one end so I could get the carbs off my V8 County.

I can take a pic of the spanner if you like.

Rebuild the original 2 x CD175 Zeneth carbies .... Forget the Holley

... Also, there is a Carby rebuilder in Morley (Located on Rudloc st)

It's easier just to remove the carbs to remove the bowls. You can't really get to much with the bowls off but bodies still in place.

Thanks to everyone .......

P38arover - picture of spanner would be appreciated.

bee utey - ever thought of moving to WA .... I'm a basic spanner turner and I'll put it on my bucket list of upgrades and personal development

mike 90 RR - thanks for lead talked to Allwest Carburetors .....he advises that their has to be some movement in carby spindles because of the different alloys and heat. Suggests replace rubber diaphragms again and look at possible other reasons for flat-spots ....

Consensus is keep the originals .....and that's my plan.

I'm away this weekend ...bugger and am suffering from withdrawal symptoms from not driving the Rangie.

Cheers

Keep the carbies, or upgrade to other RR setups... Forget the Holley, I had 350 on my Holden and it was a waste. $$$

I've been told that cams on these engines are not the longest-lived part of them... and its been darkly hinted that mine, at 200K, is around it's 'Use-by' date.

The 14CUX is supposed to be a bit easier on fuel and drive-ability. Don't put one on yours... I want to think that there's a RR out there that drinks more fuel than mine !
