Bowie69 Posted October 12, 2015 Share Posted October 12, 2015 Standard 3.9 is a very good choice for a 3.5. Genuine lifters only! Quote Link to comment Share on other sites More sharing options...
Landrovernuts Posted October 12, 2015 Share Posted October 12, 2015 I second the standard 3.9 efi cam and genuine lifters! Quote Link to comment Share on other sites More sharing options...
Disco-Ron Posted October 12, 2015 Share Posted October 12, 2015 More details required. . Are you using su carbs? Injection? . 4barrel holley or similar? ? Quote Link to comment Share on other sites More sharing options...
tonyker Posted October 13, 2015 Author Share Posted October 13, 2015 Hi sorry its on SU carbs. And im just trying to get a bit more power as its slow as hell Quote Link to comment Share on other sites More sharing options...
Bowie69 Posted October 13, 2015 Share Posted October 13, 2015 Is it set up properly now, and not worn badly? Should be reasonably nippy depending on how much weight you are carrying. Quote Link to comment Share on other sites More sharing options...
zim Posted October 13, 2015 Share Posted October 13, 2015 Carbs are your first issue. Sorry to be blunt. Swap over to an EFi engine (3.9 / 4.2 if you wish) (don't necessarily need megasquirt) and you'll gain a nice chunk of power. I reckon you can find a 3.9 for not a lot more than a new crower (or similar) cam. If you do go down the cam route, remember to change the lifters at the same time.

FridgeFreezer Posted October 13, 2015 Share Posted October 13, 2015 What Bowie said - before doing ANY upgrades at least check it's running right & nicely serviced, otherwise you're just chucking money away. Quote Link to comment Share on other sites More sharing options...
Disco-Ron Posted October 13, 2015 Share Posted October 13, 2015 A few things that I've learnt during my v8 ownership. .. ignition timing. ... ignore the timing marks, advance it til you get pinking (pre ignition detonation) under load, then retard it slightly. .. The timing marks are known to be in accurate. The carbs need to be clean getting a good fuel supply, balanced and tuned correctly with the right needles.... plug choice is also very important. And ideally genuine cap, rotor arm and leads should be used. ..... Quote Link to comment Share on other sites More sharing options...
mickeyw Posted October 14, 2015 Share Posted October 14, 2015 Carbs are your first issue. Sorry to be blunt. G Zim, I must counter your bluntness Carbs can be absolutely fine when set up well. I won't argue though that injected engines put out more power. I put a Stromberg carbed 3.5 in my old 88", and it went like a rocket, and had plenty of potential to do dangerous speeds. That was one good engine. From memory the cam was std 3.9 spec. I rebuild the heads, fitted new rings etc, so it was in good health shall we say. Now the 3.5 in my 110 was a gutless lump, that had certainly seen better days. It was also the 114bhp Defender spec version of the engine, which again put it at a disadvantage. So to the OP, I'd say to find out what spec of engine you have. There were many varaints of the 3.5, dependng on its origin. Looking at the engine number would be a start to determine this, although it may have been rebuilt to a better spec at some point. And to reiterate was others have said: Check the timing is set correctly. Do a compression test. Get someone that knows carbs (not so many of those these days I'll grant you. Do you know any retired old skool mechanics?) to look them over and check they are correctly balanced. Yes, you could pick up a cheap 3.9, but there's no guarantee that'll be in any better condition.

zim Posted October 14, 2015 Share Posted October 14, 2015 I can't disagree with the above, but for the simplicity of an RV8 efi vs the setting up of carbs etc... As well as the added power gain, that is why i wouldn't contemplate running a carb'd v8. G Quote Link to comment Share on other sites More sharing options...
Oakmaster Posted October 14, 2015 Share Posted October 14, 2015 Ive got a 3.5 V8 bolted to an LT85 in my 110 - What other V8s (and out of which donor vehicles) would be a stright swap? Thanks Quote Link to comment Share on other sites More sharing options...
Bowie69 Posted October 14, 2015 Share Posted October 14, 2015 Any other Rover V8, all same bell housing, sure you will have to muck around with oil filter housings and PAS setups, but the engine will physically fit, right up to a 5.0L TVR engine. 2 Quote Link to comment Share on other sites More sharing options...
FridgeFreezer Posted October 15, 2015 Share Posted October 15, 2015 Any V8 will fit, if it's EFi you obviously will need to do some electrics & plumbing but physically gearbox, clutch, engine mounts, exhaust are all compatible. You know it makes sense... Quote Link to comment Share on other sites More sharing options...
jai_landrover Posted October 15, 2015 Share Posted October 15, 2015 Twin Su carb should be good to flow enough for max 220bhp. I know BHP is just a bull way of comparing engines. Quote Link to comment Share on other sites More sharing options...
