I think the stock motor is good for 80 rwhp, maybe less for the later cars and
even less for a tired motor or one that is out of whack. The 100HP looks about
right for what they did. They were a bit conservative with the compression
ratio and they could easily have gotten 110 rwhp out of it which is about
right for a very drivable fast street car on pump gas and comparable with the
early PI cars.
I don't fret about these mods, they are easily reversed and you can go back to
the standard look in a few hours if you kept the bits.

Subject: Re: [6pack] DUAL WEBER 45 MCHH TRIUMPH CONVERSION KIT
Looks like a high quality kit, and I would expect it to work well,
unlike
the
Weber down draft conversion with its flow restricting "swan neck" manifolds.
Webers are superior to the Zeniths (and SUs) because they inject the
fuel in
the center of the air stream, which yields a more uniform fuel mixture. The
benefits are most evident at higher RPM on tuned engines, but are very real.
My one concern would be resale value, as modded cars typically are worth
less
than stockers, but it is your car so do what you want. Me, I prefer the stock
look.
I checked out the classic motorsports article on the conversion and it
looks
like a valid set of data, although I am a bit puzzled. Stock was 74 RWHP
which
seems low, should be about 90(?) but then the car may well have been a bit
tired. Then they modded the car, got the 0-60 to 8.4 seconds or so and said
that they had 100RWHP. This too seems a bit low to me for the HP number.
Other than that, looks groovy.
