Even or odd fire

[brad smith]

Man y'all that is a bunch of great info. I knew the forum wouldn't let me down. I appreciate all the responses. I got a grandpa fresh cutlass that needs to be brought back from the brink. It has been sitting for years. And I'm gonna save it. I want to get away from the electronics in the carb and distributor. I have always been told they just don't work well. But this the first car I have had with that set up my 70 wagon is a v6 and my 85 elco but it's tbi.
Thanks again.

It's OK, the "corporate" engine policy at gm that was coming into place really was asinine.

but the *ss-is-a 9 you say??

You can also tell by the color of the exhaust. If it's greyish it's even fire if it pinkish it's odd fire. 😂

Looks like everyone beat me to it but anyway odd fire was I believe 1977 and older, even fire 78+.

That's what I did with one of my CCC controlled engines which is an 81. Took the distributor out and all of the computer-controlled carburetor map sensor bullshit. I was told by a friend of mine that mid year 1980 engines is when they started to come with computer-controlled stuff or CCC system. So the vacuum advance engs where pre-80.
