Thanks guys,
I managed to get through to David at Galloway's, had a good chat.
I told him that my calculated compression ratio was 11.8 to 1, immediately, he believed the calculation appeared to be too high, he believed is should be 11.2 to 1.
David checked his records as he built the engine ...

Ok thanks Rob.

SbC the same cool.
I prefer NGK in my other performance engines.
Still have not worked out heat range yet.

I punched the numbers into a Compression ration calculator but using 53 cc as the combustion chamber to account for the too long thread of the spark plug.

It came back at 11.8 ...

Thanks Craig,
I will check it out.

Thanks FUD I checked it out.
Is the new engine having higher compression, or is it going to be boosted?

Anyway, I did some ccing today and have some values for people to check my calculations.

I also noticed a couple of interesting things.
Firstly I used an old ...

Thanks Craig for you detailed reply.

I see you are also using one of Harvs gaskets.

I will be calculating the static compression ratio as I picked up some placticene this arvo to measure the Dome, and I will have a crack tomorrow if I can find a graduated syringe.

I do not understand what ...

Bore.3.125 inch from memory.

Another omitted fact, the piston dome height is 8mm.

Cheers Ed.

Oh, the head has been machined past the Thumbprint.
Sorry for the inverted images, senior moment...

The block has a B prefix and I believe the head is also around that era with a heater plug and a temp sensor.

Cheers Ed.

Last ones.

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 ...
