Switch to HEI?

I have a stock 1990 Firebird Trans-Am, and I'm wondering how hard it would be to switch my ignition over to HEI. The reason i want to do this is becauseI GM HEI Cap, Rotor and Coil that i bought a long time ago. My current ignition has a remote coil.

I'm just wondering if its a matter of replacing the cap and remote coil, or replacing the entire distributor setup.

You will have to change the entire distributor. The one with the coil in the cap is a larger base.

You already have HEI.

Are you sure its already HEI. What threw me off is the remote coil, the cap i have has the coil sitting ontop of it so it made me question wether i had HEI or not.

If it's a distributor made after about 1975, it's HEI.
