Hello I just purchased a 84 coupe and have been reading a lot through the posts, I've learned that this is the only year that has this engine...

What does this mean for me??? problems????

Can I use 10w40 oil like the other vettes here in Florida?
Are there modifications I should look into????

I've already changed a bunch of components surrounding the engine but havent really touched the engine itself except for an electrical tune up.
The head gaskets need to be changed so I'll be opening it up soon...

Any input would be great..
Thanks

Wow...thank you for the trip back in time. I was in high school back in western Mass. when team Corvette took a year off, relocated the factory (I think) and came out with the new and improved 1984 Corvette. The first time I saw one driving around with "crossfire injection" on it, I thought to myself: "someday....someday I will have the potentate of the road." Well it took me 21 years, but I finally bought a C5 (2000) last November. She's an unreal machine!

I bet you can find answers to all your questions on a subsection of this board which deals only with C4 Vettes.

Hey welcome to the forum. Actually the 1982 also had the crossfire injection on the 350 engine.
The biggest problems with them were with the computers that were mounted behind the seats in one of the storage bins in close proximity to the battery, which caused corroded computer wiring harness connections due to the acidity of the air in the storage compatment. They actually got the nickname "ceasefire injection" because they were know to just quit running with the corrosion affected the microvoltage that ran the sensors. In 1984 they moved the battery up to the front side of the engine compartment and the computer was moved too. They didn't have the problems that the 1982 models did but still suffered from the bad reputation that preceded it. In 1985 they made over 250 changes in the Vette and although they look like the same car to the untrained eye Chevrolet had surveyed owners of 1984 models and made those changes. The biggest reason that they went to the tuned port injection system was a 10% increse in both horsepower and fuel mileage. The 1984 Vettes were a good car and the first of Chevrolets' changing the image of the Vette to being a world class super car that could compete with cars that cost many times what the Vette did. The only real problem with them was the harsh ride but that was because so many were sold with the rock hard suspension option that made them handle so well. The other problem was the 4+3 transmission. They had a lot of problems with them and it put the manufacturer that made it for Chevrolet out of business because of the number of warranties they had to cover, which made parts nearly impossible to get. Enjoy your '84, it is the first of its kind and one that I have fond memories of.
