ok i have a 91 z28 does my car have the regular HEi or Hei with an external coil ?? Need to know so i can order my cap and rotor and does any1 know the part numbers for the mosd cap/ rotor i need ?

 

You have all those mods done and don't know if your car has an external coil or not? J/k bustin your ***** a little. Just look at the top of the cap. If you see the coil mounted on top of the cap then you do. If you have the remote mount coil you will see what looks like a short spark plug wire running towards the passenger side of the car where your coil should be mounted on a bracket attached to the intake manifold. Hope this helps. Sorry no part number Just call summit or go to local parts store and buy accel.

 

LOL k thanx It has the external coil should be buying the cap/rotor tomorrow
