yes it does run heaps to rich, there is no leaks either, i think the 5ME has been tuned to run a little rich to give it that extra performance, that a car from the early 80's needs, it is fucking awesome tho

Umm... not sure how to tell ya this, but rich doesn't = powerful.

if it's running rich under load, you'll definately find power by pulling fuel out of the thing, until it runs at/near the ideal ratio (16:1 by mass, I think). 90's 6cyl Falcons are notoriously rich, and I've read of plenty of folks finding 10-15kw by getting a piggyback chip installed to run the thing correctly. Manufacturers like running engines rich to protect the catalytic convertor when you're towing trailers up hills, and heat soaking the bejeezus out of the exhaust for 20-40 minutes. If you've got a clever dick tweaking your piggyback, they can leave the cat-protection stuff alone, so that she'll run rich & cool if you're "up it" for extended periods.

Leaner is meaner, as they say.
