Coilbind is when the valve springs can't compress anymore. You don't want to push the limits for longevity.

Ah ok, I figured thats what it meant, but I wasn't sure. What kind of valve springs should I get with the cam then?

Dual Outlet Exhaust with Resonator Delete, Front STB, Rear STB, GMPP Trailing Arms

Depends on the cam and the heads. Stage 2 cam will work with either the 26986 comp springs, or the heads can have the spring pockets cut down .030 and use LS6 springs.

Alright, so I've compiled a final list for the spring of what I need to get. Hopefully I won't need anything else, but if you see something I missed let me know.
Critical Item:
- DHP Powrtuner or similar tuner
Engine
- Complete low mileage 3400 (not all accessories needed)
- Engine Cleaner
- Various Grades of Sandpaper
- High Temp Paint
- Various Engine Fluids
- Gaskets
- Bolts or any other small items I need as research progresses
- TCE 65MM Throttle Body
Transmission
1) 4T60E currently connected to the 3100.
2) 4T60E from the DOHC I have, rebuilt and gearing changed.
3) 4T65E from a donor car.
Exhaust
1) Dual exhaust from my Monte parts car, cut at the downpipe. Welded on with new downpipe for better flow. Paired with either 3400 manis or '05 3400 manis with 3500 port sizes.
2) Eventually I would like to get S&S headers and do a full custom exhaust, I'm going to hold off on this for a little while though.
Possible Items (Still deciding whether I want them or if they are needed)
1) New valves
2) Comp or LS6 Valvesprings
3) 60* Performance Cam
4) 60* Custom Length Pushrods
5) '05 Impala 3400 Exhaust Manifolds
I'm now debating on whether I want to get the Cam or not, as it will add about $300 to 500 on to the swap. I just figured since I was going to have the engine apart I may as well get it done instead of doing it twice. I need to work out a budget for this thing and figure out whether I can add it in.
Anything you guys think I will need or should look into aside from what I have listed here?
