HiNothing flash about the chamber design in Standard/Triumph engines back then, just a simple bathtub with a rather large squish zone. I can't remember the cam timing, but there was bags of overlap, you could feel it was there above about 2000 RPM. Ports were polished etc, bigger valves, double springs.... combustion spaces were all matched for volume. All balanced up it easily ran out over 6000 RPM and was more than a match for the local hot Holden brigade.
Triumph six cylinder engines were the same basic design - the front and back plates fitted both 6 & 4 versions
crikey, another fool....

I had a mate with a Standard 10 and we did quite a few trips around in it. Slept in the back. Took it to Bathurst, Orange, Mudgee and places around there. It was standard but I 'tuned it up' to run OK and surprisingly it cornered well on cross ply tires. The steering went all light and funny when you lifted the inside front wheel off the deck. Gees we might have done something silly if we had more power !! Very controlable though and did not loose the tail and go off backwards like a R750 The diff ran low on oil one trip and we had it replaced by a wrecker while we went shooting. That was a good days work Jaahn
