1984
The engine was just fine (used on the 1982 also), and gave the best performance for the then-current EPA restrictions GM had to work with. These engines continue to perform very well today. Basic throttle body injection.
The suspension earned the title of best handling production car for 1984. The stiff ride was the price to pay for that maneuverability. I happen to like it while others prefer a softer ride.
the OP was asking about price and 6k is pretty steep for ANY 26 year old car these days.
My point is... The early C4 is a good car, but do yourself a favor and get the 86, 87 or 88... or newer. The extra cost will be marginal and you will get a vastly superior car. The L98 with aluminum heads and a rollercam was a respectable engine. The 84 crossfire injection engine was very inferior in comparison.
I'm not saying the 84, as a car, was junk. It was revolutionary! BUT, I AM saying that compared to the Vettes made just a few years later it was undersirable. If you can afford another grand or two get an 87 and you will have a much better car.

[QUOTE=TraceZ;1575291728]I was messing with early C4s back in the late 80s when I first got my drivers license. My uncle had an 84, 86, 87 and an 88 all at the same time. The 84 was junk compared to the newer ones. It rattled the teeth out of your skull and couldn't get out of its own way if it had to.My point is...

My statements are not BS, they are 100% true. There was a carhauler that overturned on the Wisconsin interstate full of C4s in 1990. My uncle bought the entire load from the insurance company and began fixing them to sell them. I had the opportunity to check out many early year C4s and the L98 cars with the aluminum heads and rollercams were by FAR the most desirable. Nobody even wanted to look at the 84 because the throttle body injection was junk compared to the new tuned port injection. That TPI was so popular that for a decade guys swapped it into all sorts of muscle cars, even fords. TPI swaps were everywhere.
Ever see anyone swap a crossfire motor into a hotrod? Nope.
There was also a 1983 Hurst Olds on the car hauler. My dad bought it from my uncle and still owns it to this day.

As others have said, I'd keep looking and probably buy a newer C4. All have their +/-. Buy the best condition car you can find. As original with no paint work and good maintenance history as you can find.

ive had the opportunity to own early/late ones (same time)
everybody knows the which ones are FAR more desirable
its always the guys that never ever quite had a 84
that say the kraziest things about them
WHY would some body get on a 1984 TREAD
and bash the crossfire
i wonder if the c3 crowd bashed the 82?

So for fairness, I can stroke the TPI and install an Accell SuperRam manifold. Right?
There was no 83 Vette, that made the CF in the 84 a one year motor for the C4. The TPI SHOULD of been introduced in 84. It's my opinion Chevy screwed up by not giving the revolutionary C4 Corvette it's own revolutionary new fuel injection.
As a result nobody wants the 84s. That is reflected by the fact the 84 is the most affordably priced Corveete on the market.
For folks on a tight budget, that can be a good thing. As pointed out the CF can be modified to be more appealing.
I don't mean to sound like I'm hating on round taillight C4s. The round taillight C4 was the first Vette I fell in love with. The L98 was a solid power plant. The first Corvette I ever got a ride in was a blue 1984 with blue interior. I'm just not a fan of the crossfire. I love Camaros too, but I'd avoid buying a crossfire Z28 as well, and they made plenty of those.
If I had an 84 sitting out in the garage, I wouldnt sell it, I'd transplant an L98 or LT1 into it... with a ZF 6 speed.
As for all the 84 bashing by those who don't know any better..........
Let take a good look at the "vastly inferior" L-83 compared to the "it's SO great" L-98:
The L-83 has the worst cast-iron production heads ever - they flow ~155 CFM at .400 lift
An intake that reduces port size down to roughly 60% of a "normal" port by the time it gets to the flange
9:0 compression
A tiny "standard" hydraulic cam
Only 2 injectors with 2 small throttle blades (something like 1 3/4") that flow around 400 CFM.
Here is a shot of the intake ports in the manifold:
Now, the vaunted L-98:
Better heads that flow ~185 CFM at .400 lift
9.5:1 compression (supposedly 10:1 in 1991)
A hydraulic roller cam
Dual throttle blades that are almost 2" in diameter
Multi-point fuel injection - 8 injectors
I listed the flow at .400 lift because both stock cams are barely more than .400" lift, so that "matches" what they do stock.
The factory rating for the L-83 was 205 hp/290 ft/lbs of torque, and the L-98 was rated from 230/330 up to 245/345.
On top of all this (no pun intended) is the intake manifold difference. I don't want to cut and paste my whole dissertaion on the intakes, so click here to see that:
http://www.marcmedina.com/crossfire1.html
In the end, what the L-98 guys here are saying is that because of all the extra technology that the L-83 doesn't get to start, it makes (at most) 40 hp more than the L-83. OK, sure, I can live with that, HOWEVER.......
Think about this:
Even the "worst" aftermarket aluminum heads (the Edelbrock performers) will easily pick you up 20 hp over stock.
The L-83 will benefit more by adding a matching .5 point in compression.
Add that hydraulic roller into an L-83 and again you have a big gain in HP and TQ
Give the poor L-83 an intake that will at least flow enough to match those cruddy stock heads and pick up 1/2 a second or more in the 1/4 (actual results from those who have ported the stock intake), or get one of the new Renegades (for 1/3 the price of a complete, used Super Ram setup) and REALLY make some power.
The stock throttle bodies can be easily bored to 2" (52mm) to flow about 600 CFM.
You think all those other improvements won't net at least another 20 hp to "equal" the output of an L-98?
In the end you'll still have an engine that will REV - unlike the L-98's since they have those LONG runners that were designed for a 305.
Sure, in dead stock form the L-98 makes more power than the L-83 but for all the added tech it comes with, it should make a LOT more than it does.
To me, the bottom line is that a "corrected" Crossfire will run VERY well and continue to uphold the Corvette badge - and shock some L-98 guys in the process.

I'd keep looking. The top is $500, plus whatever interior work you may need will be expensive.

I always do my comparisons apples to apples however. I compare stock to stock. As easily as a crossfire can be modified, so can any other engine. Any car can be made to be fast. Any car.
You guys have openned my eyes though. I appologize for my prejudice against the 1984. You've made me do some thinking about why I feel the way I do and come to the conclusion that it's because I haven't seen a well maintained showroom condition example of a crossfire C4 in a very long time. Whenever I see one it's always beat, and shows a lot of age. A sharp factory fresh appearing 1984 would get my interest and respect. It's just been a long time sinse I've seen one. I'm sure some folks in this thread have them.
