1. Clutch spring compressor. Two vice grips with the wide jaws will do in a pinch.
2. Around here a BB cased 727 will run you about $150.
3. I like the Transtar kits but upgrade to the kolene steels and Alto Red clutches if it's for a higher horsepower build. I used to get locally from a supplier but now just go online and get them.
This might be a can of worms but I'm starting to research what I'd need to rebuild my 727 in case I hurt it on the spray this year. For 600-ish horsepower @ 4300 pounds, besides the steels/clutches you mention, is there anything else that's a must do? Billet front drum? I've already got a Cheetah RMVB that doesn't have low band apply but I never pedal the car in 1st gear and only downshift to 1st if it's creeping along, and also am trying not to do burnouts in 1st gear either.
