Just idly browsing the internet, looking at some stuff about the Koenigsegg freevalve system (http://www.freevalve.com
). Quite like the idea, ditching mechanical timing for electronic, same as you do with electronic ignition etc, and allowing for a lot more flexibility of running, faster opening/closing etc. Anyhow, for testing, they fitted the system to the B235 in a saab 9-5, a kind of grandchild of the Triumph slant-4. May just be that it's late, and I'm tired, but I found that kind of interesting, the same basic engine spawning both production 16v and electronic camless tech. Wonder if there's a particular reason they picked the saab for development; pretty esoteric choice.
