48 or 57 both great choices.

One thing that needs to be considered is that SuedeBlue has the 103" engine. If i had the 103" I'd be without a doubt also looking at the 57s, but thats not the case. I've read 100+ cam threads and the 48s/222s seem to be the go to cams for a internally stock 96" engine.

Should be just what i'am looking for since I already have a 70t rear pulley which almost gears me down to where a 30t pulley would've put me

But I do spend 90% of my riding in the 2,500-3,500 range and when i do get on it i like to rev out to 4,600-4,900 before grabbing the clutch. So you guys tell me are the 48H's cams for me? or should i be looking else where?

I really like my 48's. They're close to 100 ft. lbs. at 2200, and still at 90 at 4500. This dyno run was done at 5,000 feet on a 95 degree day, with a slipping clutch, so the numbers might be a bit better. As I said, I really like it, and think it suits "real world" riding very well.

As far as the torque of the 57's coming on around the same place as the 48's: As a general rule of thumb, how early the torque comes on is governed by when the intake valve closes. The earlier the close, the earlier the torque, and vice versa. The 48's close at 29 degrees ABDC, and the 57's close 38 degrees ABDC. That is a generality, of course.
