Ok so tonight I finially got my whole engine back together. Anyway it didnt want to start really well at all. So I adjusted the distributer cap alittle and she started perfectly. Does anyone have a link with instructions on how set the timing?

from p 1-22 of my haynes:
read the VECI label inside the decklid for specs. mine (84 duke, manual) says 8* btdc.
paint the appropriate mark on the timing tab and the notch on the front pulley so they are plainly visible
run the engine until it warms up, shut it off.
jumper terminals a&b on the aldl. the "check engine" light will flash
connect the timing light to plug wire #1
start the engine, record the current setting.
move the light to plug wire 4, record the setting
add the two settings, divide by 2, if this is not = the label specs, adjust the timing.
loosen the distributor holddown bolt.
connect the light to #1 again.
rotate the distributor until the mark on the pulley aligns with the mark on the tab.(this is where i stopped.)
recheck and repeat until the average of 1 and 4 are the specified setting.
tighten the bolt and remove the aldl jumper.

Yes, that's pretty much the same procedure for the 2.8.

For the 2.8 it's 10* BTDC. But what is lost if you only set the timing based on plug #1 and not the average of # 1 and #4? Does it really matter? Ed

The index grooves cut into the harmonic balancer can move a degree due to tolerances at manufacture, so averaging the two is a way to make sure that the timing is as close as it's likely to get.

Thanks for all the help guys! The Fiero is up and the engine is running perfectly! My luck would of been that I got the engine together and would of spent a week figureing out why it wouldnt start. Lucky first try with some adjustments to the timeing and was all set.
