Red face Does these camshafts fit on my tbs?

They are 1999 daytona 955:s Camshafts

If they do fit. and fitted onto my bike what happens? A lot of re jetting and...

If everything done correctly. How much horsepower and torque more?

Looking at the parts fiche from World of Triumph, the first generation 955 Daytonas and Speed Triples used the same camshafts.
So, according to everything that I've been told, they should fit in your 885 engine.

I bought cams from a 2001 Speed Triple for my TBS. 38 teeth on the cam gear.

As far as the hp and torque numbers? I don't know. I haven't done it yet.
I'm getting parts together:
pod filters

I've been told I should be able to squeeze out close to 90 HP at the rear wheel with what I'm going to do. We'll see....

Note both these camshafts are more agressive than the 'green' cams of the 98hp T3s. The Daytona ones more so than the S3. (Same lift, more duration.)

I posted a pdf before (which I got from here originally) with the details of duration & overlap.

Definitely rejetting required, but from what I've seen, air intake mods have at least as much influence on main jet sizing (if not more) as cams.

Spoke with my local dealer a few weeks ago about this. They gave me a dyno sheet and a long story about a TBS. Yes they will fit is the short. The long answer is that they used the 955 daytona intake cam but swapped in a T509 green exhaust cam to gain back a little midrange. I'll see if I can find the sheet, but I'm sure it was 87hp when finished with a nice curve.
