I'd like to point out a few details re the heads.
Being made in Melbourne, Australia it means AzCoupe isn't able just to drop in and hustle them along.
They're designed and will be founded by a company with one of the world's best pedigrees in head design and manufacture. It's not like they're designing something then jobbing it out to a third world country with little respect for intrinsic quality.
The order pool is comparatively small. We as FordSixers, need to be aware that a company who make most of their income from V-8 heads will tend to focus primarily on the big hitters - especially when global economic situations appear to be changing (not necessarily for the better).
I don't know anything about the supplier's corporate structure or finance but they're not insolvent when I last looked. Nor has AzCoupe taken deposits off people with an eye to delivering product.
All in, it's a pretty straight up process. Just that nothing to report, is nothing to report. Surely that's better than the computer industry promising stuff "real soon now"?
Cheers, Adam.
