“ Already done - it came out of a Range Rover and has the little cut outs in the inlet ports where the injectors sit. The other part is the CR stampede in the block. See - that makes me sound like an expert!”

...and both features shared with the 3.5.

Thanks again - all useful and will be used when we get to the cam choice.


The first question....

I don't have masses of spares lying around or the bits from the donor vehicle that the engine came out of.

What spec bolts should I be looking for to connect the engine to the stand? One thing I found is bell housing bolts - 3/8 UNF 90 V8 CSW - 1988

Oh yes - a little knowledge is a dangerous thing, and I'm positively lethal!! Laughing

I should've said - I did check that too before committing money - it starts 36D2 and has the correct CR. 90 V8 CSW - 1988

Having a load of spares doesn't always help you Rolling with laughter

From memory I used 3/8" UNC x 4" socket cap, high tensile bolts to mount my 4.6 onto the engine stand. The length you need will depend on the engine stand you have but you can always pack them out with washers etc.

I think you'll find its a UNC thread into the block and a UNF thread on the gearbox end of the stud. 1985 127 V8 Build Thread

Excellent thanks

I usually find the more spares I have it just takes longer to find out I haven't got what I need...... Laughing 90 V8 CSW - 1988

Thanks, I’ve just added some twin port manifolds to improve the sound and they will be in place for the new motor. 90 V8 CSW - 1988

So, after a while the block and heads have gone for testing.

The bad news is it will need a re-bore. I suppose actually it's not all that bad as the new pistons will mean a more 'complete' re-build.

The next step will be to get the block machined, heads skimmed and valve guides done.

Then we get to the choice of cam Laughing 90 V8 CSW - 1988

Pressure testing has confirmed it's a sound motor.

Shopping list:
Re-bore
Re face the block
New pistons & rings
Valve guides
Skim heads - to match the refaced block, not for any desire to up the CR

Need to choose a cam next - my initial thoughts are to go for a real steel Hurricane. Improved low end torque and it's going in a carb'ed engine. 90 V8 CSW - 1988

New pistons landing shortly - it's been a while and the rest has been done.

Let's hope the next update is a bit quicker....... Laughing 90 V8 CSW - 1988

It's a std 3.9 9.35 block which has been re-bored, decked, the heads have been skimmed as well. That alone will up the CR a bit further. It's staying on carbs and I'd like to keep the drivability of the V8 so not too peaky.

Question: What Cam?

Is the Real Steel Hurricane any good or should I be looking at a Kent H180? 90 V8 CSW - 1988

Well, all the bits have been collected from the machine shop.

Now need to source the cam, water pump, assembly lube, gaskets etc to put it all back together in time for an event on 20 August.

I think you're doing a great job Ranger, sussing everything out before you actually do something,....takes a bit of patience, but ensures the end result is what you want.
I saw on one of your earlier posts that you wanted to keep the exterior of the engine looking stock, I was just wondering whether you would consider a set of pipes, even a larger 2" single exhaust with a decent "sports" or similar "straight through" muffler would enable that V8 to work a bit better & give you that lovely V8 rumble.

It's something that's always been on the wish list - the first step would be a sports system instead of the TD5 one that's on it.

However, at the moment with the larger twin port manifolds it's actually doing OK and together with the needle change has really given the old bus more character and drivability.

I'm going to wait until the engine swap is finished and see how it performs, then once all the bills are paid I can look at further upgrades Very Happy 90 V8 CSW - 1988
