The Series 2 develops it'* power alot higher. I'm assuming this is where you're getting your information. I would normally let this go after some time, but we can't afford to have someone else get this into their heads and not know any better.

the cam in question I would be installing says its power band goes to 6000 RPM......so why wouldnt I want it to shift at 5800-6000 rpm?

Sorry if I didnt say it, but I am planning on putting in heavier springs along with the rebuild.....and the stock 4T60E is friggin brand new with a 30000 mile warranty (which I have been guaranteed by my buddy the service manager at the shop it was installed wouldnt be voided by modding my car) he told me they upgrade a few things when GM Goodwrench remanufacturs them, so it should hold up a bit better than stock. I am however starting to think maby 5700 shift points with all these mods and a 5800 rev limeter. Plus if I didnt mention i think ill do the MSD DIS4 ignition hooked up to the 8224s.......but this all depends now upon how much christmas cash I get...hehehe.......Christmas present to myself.

mmm unless they did a performance rebuild the only things they "update" are the sensors, valve body, and a few other nick nacks. It probably won't blow the first time you punch it but it was too weak to handle stock output, try modified with higher revs....I dunno, I know of at least one other guy that modded his engine and blew the trans. Your call

94:
max shift speed (4T60)
1-2: 6000 rpm
2-3: 5800 rpm
3-4: 5200 rpm
this was in 97
max shift speed (4T60)
1-2: 6375 rpm
2-3 6300 rpm
3-4 5200 rpm
just something to think about before you set your sights on any specific shift point.
anyhew, if I had a series I, some money, and some time, I'd be all over these deals
I actually came pretty close this past weekend to picking up a 93 bonnie, but it didn't quite pan out.
