Hi guy photos attached,
Please add comments or advice about the carbys if you spot any issues.
They are going on a humpy so no battery or heater box to worry about.

Thanks guy fot the replies.
Well, I did buy the carbys.

I will post pictures today.

The advice is appreciated.
The setup does have round throttle shafts and there is evidence of slippage with different screws fitted to the W clamps.
The guy who sold them to me explained the basic operation of ...

Thanks errol62 for your Input.

I am going to look at the carbs this morning, I will check the throttle shafts for wear.
The owner bought the carbys a long time ago and he has no history of the previous tuning of the Engine or that build, if any.
He did use the to run a cam in on a stand recently ...

Thanks Harv,
That chart is excellent.
So the 1 1/4 should do the job.

I have read different things about SU carbys.
Some say they are excellent when set up properly.

Others say they don't stay in tune and need regular retuning.

I rang a carby specialist and he said it was hard for him to get ...

Hi guys,
I might be able to get hold of a set of 1 1/4 triple SU carbys on a manifold to suit a grey motor.
Does anyone know what sort of horsepower they will be good for?

Cheers in advance.

Thanks Rob,
I am coming back to Holden Six cylinders after 40+ years away from them and even then Grey Motored Cars back then were bought for $40.00 with a couple of months rego, and, driven into the ground by very naughty 15 year olds.
Red motored Holdens performed far better and people would get ...

Thanks Rob,

Very important and detailed information.

I was talking to Richard Wallace about a month ago and he also warned me about the issue of Oil Drain back issues and described what happened to him previously when he first put the J Motor into his Humpy.

I didn`t get a great detail from him ...

Thanks Errol62,
I had compiled a long reply about 10 days ago only for it to be lost in Hyperspace.

Great fun when it happens,
Anyway, yes, I am hoping the Crank is Parallel to the Deck.
I am also assuming the J block, being from the EJ has better machining Tolerances than earlier Grey Motors ...

Great Pictures Blacky off the normal route taken by most travellers.
I might consider that route later although the Humpy is not ready for such a trip.
Golden Fleece Ute for the win so far.

I have been wondering how the Engine Temp has been going at Speed as you have A temperature gauge fitted.
Are ...

Thanks Blackie, that Fan blade will be great.
Iam going away again to work soon, I will send you a PM to organise pick up.

Yeah, not sure about deck the block, still inspecting the block haven't found any reason yet to do any machining.
Ignorance is bliss.
The J Motor is low miles as you saw.
When ...

Hi guys
I went and picked up some motivation from Galloway Engines this morning.
Mild performance EJ Head, Red Motor valves, hardened seats back cut valves, throated etc..
The head has been machined down nearly to the Thumbprint.
The pistons are 40 thousands in the hole, I would love to zero deck ...

Good information there Rob.
I did not realise that there were better Grey Motor Oil Pumps.
So, after FB Engine number B47171, Engines had the better Oil Pump Part number 7405904.
which has different body and different helix gear angles producing higher Oil pressure at lower RPM.

Cheers Ed.

Thanks Rob

I will have a look at those pumps.
I am just chasing a little bit more volume and pressure without stressing the Dizzy gear too much.
It is a J motor so it has the Oil squirter onto the gear which will help a bit.

I will look at those post
cheers Ed.

Yes Blacky, it would be great to buy new pumps off the shelf, especially if the were larger volume without loading up the distributor gear too much.
A deeper pan might also be an option as well so to not circulate sludge so much if not using an oil filter.
The chev pumps are not expensive might be ...
