I'm also doing my timing @ the moment but i also don't know how it works. I'm running a T285 cam from piper cams, but off the info from the site i just don't know how they have to be set!

iirc set it retarded it lowers the powerband down the scale, gives a bit more oomph n torque but looses a bit of top end
and advancing is the opposite, looses a bit of bottom end, pushes the powerband up a bit and gives a little more oomph at the top end.
if its an aftermarket cam (iirc also) kent cams are ground to a 4degree advance on standard cams anyway.
just be careful not to crank it too far and bend ur valves!!!

If you are dialling in the cam, you need a timing disc and a DIAL GAUGE.
YOu set the cam so thatis has FULL LIFT at whatever the cam makers says, after first establishing the TRUE TDC with GAUGE, you then turn it til it is at the right amount of degress before/after TDC, then turn cam till it's at correct LIFT on lobe.
An easier way is to do this though,
Get an old piece of metal that controls the cam end float, weld a nut on it, put the belt on etc with std pulley all timed up right, insert bolt into nut so it contacts the cam surface tighten, take off pulley etc this will hold it at TDC, put new pulley on tension up.
This is a cheat I always did with pinto cams, the bolt will contact the cam on a part that is not a bearing surface so is ok.
STD setting will be fine unless stated otherwise, they will not move the tag position around , will always be zeroed to keyway as normal.

im runnin a piper bp 285 t2 mate so probs the same

the only true way to st the cam timing is with the use of a rolling road... as you can have repeatable power runs to extract the best from your particular set up
