Six Cylinder High Compression Engines

[GT6Craig]

So what is the thought on the 'HE' designation on some Triumph engine codes?

The general opinion seems to be that it stands for high compression engine.

Would this be standard fayre in UK GT6's? Does "HE" make an engine any more rare or valuable?

Cheers!

I thought most of them were HE suffix engines.  Casper's Herald apart, I've yet to see a LE suffix engine in a Triumph.  I know that they exist but I was under the impression that they were primarily for non Home Market use.

Yes, I think America got most of them.    ;)

Standard for a UK spec GT6.

LE engines were primarily for markets where fuel quality was likely to be an issue. I previously owned a personal export 948 which had been exported to Yugoslavia, then later returned to the UK - this had an LE engine.
The vast majority of home market Triumphs will have HE engines. The simple E suffix was used on some of the earliest Heralds as well as some TRs, but from the early 60s onwards, anything other than HE would be an anomaly in the home market,

No, we usually got "HE" engines until emissions standards started choking down the engines in the 1970s, at which point we usually got unique "UE" engines (United States Engine -- or maybe Emissions  ;) ).
