CrossFire rumors
I have heard a lot of bad stuff about the crossfire injection of '84 - '85. I've heard they are hard to tune, do not run well, and are expensive to fix. Can anyone tell me if there is any truth to this?

depends
some guys here love em - we had one on an 82 C-3 - played with it for a month - then turned it into a boat anchor - went carbureated - runs a whole lot better now! I wouldn't mess with it - If I was going to put that much time in to something - I would want and expect a better outcome.

Such is the case for any motor with low production numbers. You think Crossfire is dissed, look for CFI 5.0 Fords. They don't get any attention becauses they're all dead and buried. And Ford dumped it after 2 years.

Nothing wrong with 84's.
They are fairly reliabe motors when they are running right. Not really that complicated to work on.
I wouldn't think they were anymore expensive to maintain then any of teh other model year Vettes. Occasionally, it may be harder to find a part since the Crossfire was only available two model years, but other than that...
A lot of people bad mouth the Crossfire. In stock form, it has a couple of design issues that keep it from making good high-end power. So it's probably the slowest of the C4's. But for it's time period, it was one of the fastest cars on the road in 84. It also had more HP than it's predeccessor. Other people that bad mouth it are usually just doing so because "everyone else does" and don't really have a clue what they're talking about.

My mistake. I guess you do learn something every day.

I think it is safe to say that we all love our specific model year C4s for different reasons. It would be interesting to find out why each of us chose our respective cars.
For me, I bought an '84 because I starting working for Chevrolet at the end of 1984. At the time, I was with the customer assistance center and talked to a lot of customers about the experiences (you might think that would steer me away from and '84!). Guess it is a memory thing. Plus, I thought the Crossfire setup was pretty cool at the time, and that just stuck with me. This is probably the topic of a different thread, but maybe it is also a good way to divert negative attention from the Crossfire!!

He noticed my "Little Red Corvette t-shirt" when I stopped in for some post cards. Nice guy.
cool! that guys name is Tom and he's a member over at the crossfire injection vault. he does 14.60's with a few minor free mods and some old flowmasters. thats running right with a stock TPI in some years and his cars got that "JUNK CFI" everyone talks about. its really quite reliable and VERY simple. my CFI vette is faster than my modified old 87' vette and i have less mods on the 84' than i did on my 87'! and the 87' had a fresh rebuild and new exhaust.

Also remember, for every one that junks the crossfire, there is one less original 84 out there.
I sold my 84 ONLY because I found a great deal on the 87 Convertible. Even though I do love the power increase I got in the 87, I do miss the 84's tighter steering and uniqueness in the crossfire motor. I wouldn't have sold it for the 87 if it wasn't for the convertible factor.
The people that complain and say its junk are both uninformed and also probably forget that the car is 21 years old. Do we really need to remember the options that were out there back in 1984??????

I bought my 84 last year from the orig. owner with 67,800 miles. I'm up to 72,500 now and run it up to the 110-115 range monthly. Never hesitates and i've had no problems with it. thanks Leonard for taking such good care of it!
