Well here's a story that will make Dave cringe!

Back a while I had a '47 coupe with Y-block running gear through-out.

I let a kid use it for a rod-run and it blew a head-gasket between two cylinders, he drove it like that for near on 400 miles.

When I got it back and took the head off I found a deep groove on top of the block between the two cylinders.

So, being 'financially challenged' at the time I fixed it thus:

Towed the '47 to a mate who is an engineer and after we blocked off all the holes on the engine my mate used the proper rods to build up the groove to just proud of the block.

Then we ground back the weld with an angle grinder until it was almost flush - and dressed it off with a long fine-toothed file.

And before replacing the head-gasket I placed a 4" length of copper wire between the two cylinders before gluing verythign together.

That old 272 fired right up and never missed a beat, I eventually replaced the 272 with a 289 but that's another story...

I know they produced Y-Blocks in Australia for a lot longer than we did. I also know that South America produced them as well.

The two center exhaust ports were always a major heat problem. The gasket set I got from FelPro had 'steam holes' in it. They suggested I use the new head gasket as a template to drill holes in the heads and both block decks for better cooling.

In S. America (Argentina, I think), they came up with a new head, similar to a 289 head, with the center exhaust ports re-configured.

My '55 came with a 272. I still have it on a stand. It's old and tired but original.

I admire all you guys down under, for making things work from zero resources. I love stories like your Y-Block story. That copper wire was the best heat conduit your 272 ever saw! - Dave
