I am going to be buying an opti just wondering which are the best ones i should be looking at.

 

Msd 8381

 

Stock AC Delco Replacement

 

Forums are filled with this question asked over and over. Take some time to search/read other threads. That's what they are there for.

I agree with post #3.

 

I just ordered...not received yet though a Delphi unit from Amazon.com.

Delphi CZ20003 Distributor $252.96

 

Delphi = AC Delco from what I've read.

 

Delphi is not the same as Delco, since 1999 Delphi has been independent of GM.

Look carefully at your link:

Delphi owns the Delco name.

 

It's dangerous to believe anything posted on Wikipedia...it's full of errors and can be edited by anyone.


The Delphi business ia a wholly owned subsidiary of the General. Delphi is, in fact, the same as AC Delco..

 

It's a little more complicated than that:

Not to rehash the old debate again but since you have a 94, the MSD gives you the vent option without having to change all of the parts. All other things being equal, this is one good reason to go with MSD.

I am in the middle of doing a rebuild and I have my MSD with 100,000 miles on the bench. Still works great even after degreasing and washing my engine several times. Other than my initial problem out of the box, it has been very reliable for me.

After going through 2 replacement AC Delco units before finding the MSD, I'll never go back.

Great article. I think they misidentified the old and new timing covers in the picture. The newer cover has the larger hole right?
