The V8 Owners Forum -

What fuel pressure regulator are you using, and have you recently checked the timing? I had constant problems with a Holley fuel pressure regulator so will never use one again when Filter King make a much better product, and I also had backfires caused by not enough advance (albeit a blower engine ...

Hi

Went for a longish drive yesterday and while following a tractor at about 40mph I had a large (and quite alarming!) backfire which seemed to come from the engine bay (manifold?) but difficult to say. It certainly didn't seem to come out the back (I have a GD with underslung exhausts). I drove ...

Thanks guys, thats really helpful.

Hi
Can someone give me an idea about what sort of price I should be asking for the following:

Tuned turnkey engine including gearbox. Ready to install and fire up.

Rover 3.5 V8 Engine (SD1)
Recon LT77 gearbox and Bellhousing
V8 Developements Stage 3 big valve heads
Viper Hurricane Cam
Crane "High ...

If the tool is too short, then yes, it won't work as the engine will be free to rotate.

But if the tool is long enough to hit the piston, then it works fine.

Chris.

Sorry to bang on about this. But if the tool is to long and the piston hits it, then you are not at TDC. So you back it off a bit ...

Doesnt really matter how long the stop is, although if its waay too long or short you will have problems.

The critical thing is that you rotate the engine by hand one way until it hits the stop, mark the position on the crank pulley as accurately as possible.

Now rotate the engine the other way ...

So you need true TDC then.

I've lost count of the TDC tools I've made and lent out over the years.

I make mine by cutting the earth strap off a spark plug. Then break away the porcelain and a good chunk of the centre electrode. I like to ba able to push an old bolt or bit of stud about 5mm into ...

Actually Pete, the mist is starting to clear!!! Thanks mate, I think I am starting to understand. (putting it into practice is something else though!!!).
One quick question, while gathering bits for the new engine, what dizzy would you suggest? Don't think I will stretch my knowledge going with ...

You want to be running more than 30 degrees on a 3.5 lump, 36 would be a better bet. I have also found that they idle is best with around 14. (quite a bit more than Rover specify).

The Eddy 500 carb that you are running does not suit the Lucas vac advance very well at all. You are best off not ...

Hi

Yes the engine runs and seems fine. Just feel from what people have said that maybe it will run better (?) with the right timing setup.

thanks

Hi

I am trying to understand ignition timing but am struggling!! There are a few very knowledgeable guys on the forums I use, who have helped me massively, but I am still not sure about the timing side. I have a RV8 3.5. how do I know what the total advance timing should be set at? I have just ...

With regards to EFI, if it was a system using throttle bodies then that would be a good setup but if it was a system using a single throttle plate then the gains over a well setup carb will not be all that great. (Note 'well setup carb' and this is only my opinion!!!).

Martin, as you already have ...

I suspect that webers of the right size would give you a fair bit more BHP than a Eddy 500 but they will cost you a hell of a lot of money! Also every single time you want to make a jet change that's 8 jets that you need to buy.

Well setup webers will give you very good 'pick up' and a low ...

Hi

Just a general inquiry for my interest, but can anyone tell me the performance benefits and fuel consumption difference between a set of Quad Webers and an Edelbrock 500 on a large Rover v8 engine in a Cobra replica or similar? Also I assume the Webers would be a nightmare to set up?

Thanks ...
