Engine number chart

[colt]

Ok, I used to be able to find this chart, but now I can't. It is a chart someone here made up of all red motor engine no. prefixes.
Having received another 173 (thanks John) I'd like to know what it came out of. Prefix HD. But can someone please find the chart?

Here's a JPG of a PDF I nicked from a Torana site, seems to indicate you have a Torrie motor there.

Thanks, Stinky. And to Dr. Terry for compiling.

Hi Collin,
Are you building something new or is this motor going where a grey should be!!

Stinky,

You might have got it from a Torana site, but it's originally my work, published in the NSW Club magazine Sideplate, Vol 24 No 2 to be precise. Unlike the article itself, I bet wherever you got it from failed to attribute its sources.

The forum referred to in the article is this one.

  I assumed that I nicked it from a torrie site as there were credits for the torrie sites in the text, I did get it from the 'net somewhere.
Having just checked the original PDF I have and although it is a single page document with the page number partly cut-off the PDF details "Richard Thomas" as the author.
Sorry for any confusion.

My apologies, Richard. A very handy chart.

Weddo, I would NEVER put a red where a grey should go. I'm building an Appendix J EH and am on the lookout for any 173 as theyre a better starting block than  the 179 & easier to keep under 3 litres (the limit for an EH in App J).

Colin, dumb question time. Why is a 173 block better?

Cheers

The external ribbing is meatier, which makes the block itself stiffer,
It's getting hard to find 179 blocks which haven;t already been bored, you can bascally only bore them once before they go over 3 lts.
The 173 I just picked up is a standard motor, original bearings and pistons. Because no-one does up 173s you usually get an engine that hasn't had a hard life, youre starting with an engine that has plenty of life left, barring major failures you should get several rebuilds before you need another block. I have now got 3 173's. They are all standard, no rebuilds. I can't remember the last time I saw a run of the mill red (179,186,202) with all original bits.
In class Nb they are now letting us go to 186 standard. The same applies. When was the last time you saw a 186 with a standard bore.
You need to start with a smaller block & bore it up to 186 standard, no overbores.
Crankshafts out of the smaller capacity engines are the best to use because they are usually in commercial vehicles (149,161,173), they usually haven't had a hard life, as are the cranks out of 138 reds because they don't make enough horsepower to have had a hard life.
The only thing to watch for with 173's is that the later engines have the large main bearing journal size, which limits you to cranks.
Colin.
