Be interesting to see what engine you eventually end up using XD

The fuel filler in the door jamb shouldn't be fumy if you use a sealed cap and run the tank breather line under the car somewhere like the early model utes and chuck a fuel filter on the end of it to keep it from breathing crap into the tank.

What axles did you use?

Turn 2 A10's into an A20 = finally Australian street legal V8

Looks like bits of bearing cage

I think you'll find that belt is probably for the early model A12 with the alternator mounted on the manifold side of the engine

Also, I think Chris Lyons (clyons on here?) may have made that manifold, or at least he made some steam pipe ones much like that.

Almost all ignition+fuel ECU's have fully customizable ignition maps, you can even get them to advance according to readings from the MAP sensor. If you were going to go carby turbo, you can get programmable MSD modules which are basically an ignition-only ECU, same deal, fully customizable maps + advance and retard according to MAP readings, for a fraction of the price of an ECU.

From what I've read so far in the book I mentioned earlier, square ports have poor flow characteristics. I think the only reason most manufacturers use square ports is because of space limitations. Chev did it because of the pushrod location. I think the book even mentions filling them to an oval-ish shape drastically improves the flow. Definitely worth having a look at the book.

In the not too distant future I'm hoping to try a few different standard heads on a 'control' engine in a car on a dyno to see what figures each one makes.

I'm also hoping to port a round port using the info from the book 'performance 4 stroke tuning' by A. Graham Bell to see how it goes vs standard.

I don't know of any places near me to test them on a flow bench unfortunately, would be much better I'm guessing, less variables and whatnot.

Surprised after all these years that noone has done it before and posted the results in tech wiki.

So your Pulsar/Cherries and B210's never had the late A12's?
