Andrews 21H in TC96 bagger

Andrews 21H in TC96 bagger
Has anyone installed Andrews 21H cams in a TC96 bagger? I'm asking because I have the opportunity to buy a set of 21H's for $210. Here is my present configuration:
Stock TC96 except:
1. Jackpot mufflers
2. PCV with Auto-Tune
3. SE AC w/cleanable element
Conditions and what I want to accomplish:
1. Will probably reuse stock pushrods.
2. I want no loss of low-end or midrange anywhere in the chart.
3. Need an increase of 5 ft. lbs. of TQ or more from 2300-4000 RPM.
4. I'm not concerned with peak HP, just TQ between 2300 and 4000 RPM. I would basically like to see my TQ chart move up without skewing to the right, and looking like a long rolling hill instead of Pike's Peak.
Questions:
1. Will this cam accomplish this? Has anyone installed these cams without other engine mods?
2. What will be the effect on peak HP, although not my primary concern. I wouldn't think it would change HP much.
3. Does anyone have a before-after dyno chart on a TC96 (stock comp. and heads) with these cams?
4. Is it necessary to replace the stock inner bearings with either new stock or Torrington B-168? I don't have a bearing puller/installer for this engine, only for the B-148's (TC88).
Here is the dyno chart for my existing setup:

For your combo I would go with Andrews 26 you will like it better. The 26 is a good cam. It has a better ranger of power 1800-5200 rpm. ABDC is 35 for the 26. The 21 is 1700-4800rpm with less tq. ABCD is 30 you will see a little more tq of the start with the 21 but it wont hold like the 26 will.

The direction you are looking, I would look into a Woods Cam. Woods TW-6. But I would use adjustable pushrods, just to have them. Could even use Quickie types.
Pure Torque. Lower lift, bolt in, version of the 7H. From low RPM's, 1500 up, I don't think you can get much more without a supercharger.

Not to contradict, only mention that we have been seeing great results with a Wood 6-6, combined with a 4* advanced gear. Currently doing the 4th one of those this year.
Great early torque, that continunes to carry out.

I know the 26 is a good cam, and many riders of TC88's have used them with success. But the 26 will move the TQ curve to the right and I don't want that, or at least I want to minimize it. I don't care about anything above 4000 RPM as long as peak HP isn't worse, which isn't likely. I secretly would like a boost in HP, but not at the expense of the low-end.

Anyway, the TW6-6 and 4° gear is out of my budget range, over $500. I can afford the $210 for the TW21's I've found, but I'm still not convinced they will work as needed. The specs suggest that they might, but I have not seen any dyno curves from any source, and Andrews either has none or won't release them.

I had the Andrews26 cams on my 96"
They work great out of the hole-4500rpm's After that they run out of juice. They are really good if your not porting or bumping up the compression. Basicly I think they are great for the 96". Your bike will run quite a bit cooler than stock. You'll see why when you take out the stock cams. They are junk. No cam overlap, no duration and very hard on your engine. I would not have changed the 26's, but I went to a 103"
The 26's don't work well with the 103" with porting. They just don't deliver enough fuel when she starts breathing. Went with the 37's. Again 26's Nice cams. I have a set in the cam support plate with very few miles if you're interested. Whole package $150.00 + shipping
