GT6 TR6 GT6 Quoted HP More Triumph Trivia

About 1972 or so the quoted HP for the GT6 dropped from 95 to 79. Some if not all of the change was attributed to a change from using Gross to SAE net HP ratings, something that I think most if not all manufacturers did when quoting HP in the USA about this time.

My question is why didn't the TR6 see a similar drop, quoted HP for the TR6 stayed in the 100+ range in the USA throughout production.

I know they did some changes to camshaft and exhaust through the TR6 production, was this enough to more or less overcome the change from gross to net HP quoted? I am guessing not or the later cars actuallyy would have been a litle faster than the early ones. Or maybe Triumph fudging a little to keep the TR6 over 100 quoted HP. But if they fudged on the TR6 why not on the GT6?

Any knowledge of this out there? or discussion/educated guesses?

TR6 = 2.5 Liters
GT6 = 2.0 Liters

Could have something to do with it
