I have an 82 z28 CFI that I just rebuilt and the only thing I have left to do is replace the ugly air cleaner. I'm looking for something chrome. Two round air cleaners. Anyone know the specs I need or maybe some part numbers? Any help would be awesome. Thanks

You could get yours chromed, you could also look at the air cleaners that go on to 82 & 84 vettes. Another thing you can do is shop the junkyards for 4 cyl. tbi air cleaners, cut them up & make them an open element style.

I've seen people with two little edelbrock air cleaners on their crossfire. It looks a lot better

That ugly air cleaner serves a function by sealing up to the hood scoops. Im not an expert but is it gonna run differently with out the hood scoops sealed to the aircleaner?

82_Camaro

yea i know but i kind of intended on getting a different hood as well

Strangely,my factory shop manual has an illustration
of the crossfire air cleaner with a snap-on plastic
cover over basicly the same air cleaner that these cars
came out with-must have been an idea that never
made production as i have never seen one with the
plastic cover-not even on the C/F prototypes...
I ran an '84 vette air cleaner on my car for a while,but
had to notch the cover to clear IIRC,the wiper motor.

hmm yea i think im just going to stick with what i had because i cant find anything else. and i wonder what other kinds of things they came out with that never hit the streets

You're definitely going to run into problems with another air cleaner, especially if you don't change the hood right away. First problem I see is clearance. you may have noticed that the CFI air cleaner isn't as tall as the LG4/L69. The manifold sits higher and there's the added issue of the hood induction, so the result is a pair of comparably thin filters, which you'll also run into problems finding suitable replacements for unless you get the K&N kit. There is no generic fram filter for this car. If you do try to go that way, you'll have to fabricate something to fit the TBI units for a good seal. I personally have not seen it done, but I suppose someone has probably done it.

It's important with this system to have a good tight seal with your filters, not to mention the hood scoop. Those flaps aren't just for show, they serve a definite purpose. One thing you'll notice about your CFI setup is that it doesn't have a snorkel leading to the intake like all the other cars do. This means that you're sucking lukewarm engine bay air all the time unless you're at WOT and the flaps open. That is fresh cold air coming in and if you don't have a tight seal to your air cleaner through there you are throwing away horsepower, something your car is already seriously lacking.

Fantastic

Thanks

By your car lacking horsepower, I was referring to all of ours in stock form, mine included lol

82_Camaro

Yea I know but hopefully with everything I did to it I get at least 250. Doubtful but i can hope

You should be able to pull 250 with those mods, if your computer has been tuned also

You forgot to add 'port the heak out of the intake'.

82_Camaro

do you know anyone who does a good tune for crossfire? i have yet to do anything with it.

8t2 z-chev

a good porting job on the stock intake makes a huge
difference with a crossfire;did a manifold modification
and port job(had to add some extra metal to the port
intakes to get the radiused shape i wanted) on the '84
vette CFI 350 in my car and that along with a mild
port job on the heads really woke it up from the
original 205 HP rating more recently the fuel pump
has been upgraded.My ECM has a hypertech chip,but
that is the only(very minor) change from stock tune
Base timing,fuel pressure,injectors, can be tweaked
some to suit modifications.

82_Camaro

all i did to the intake was sand blast it and clear coat it

8t2 z-chev

The stock crossfire manifold is a major restriction-
the cross section of the runners is pretty small,but
one of the worse aspects is the way the entrance to
each runner is cast/shaped with the sharp,non radiused
edge to restict and disturb mixture flow...Next time you
have the manifold off,would be good to work it over with
a die grinder a little to improve the problem areas.You
could also obtain a spare manifold to work on while the
stock one remains in service until the ported one is
ready One thing that is good about the crossfire
manifold design is the runners are a pretty straight
shot to the head intake ports,helping flow and velocity.
The intake work on my 350 crossfire increased the
usable RPM by about 1200 rpm besides the very
substantial HP and torque increases.

82_Camaro

i was thinking about the renegade intake. any thoughts

tlandoe

Don't bother with it. I just sold mine and put my stock one back on. For half the price you can port it just fine and use the extra cash on your heads. And you don't want to wait that long. I sold mine secondhand for 600 to a guy who just couldn't wait.

8t2 z-chev

the renegade is very good-i have seen lots of pics of the
runners and runner intakes and they look good
Avalibility of the renegade was spotty last year but i
hear some foundry problems and other issues have been
solved and manifold is back in production.
I did my manifold work back in 1995 and the whole
operation was a bit of an ordeal with all the welding and
grinding-if the renegade was avalible back then would
have saved me a lot of work! the renegade is better than
my heavily reworked stocker too.

82_Camaro

cool ill port mine. I'm going to wait till the winter though and drive in this summer

when i ported mine an electric die grinder was used
with 6"long martendale carbide burrs,i hooked the
die grinder to a varible speed control so the burr was
easier to control and to prevent the burr"loading up"
with aluminum-removed about 1/8"from most port
internal surfaces,a little more in certain areas.built up
the runner intakes to enlarge and give a nice flare
shape with thick rounded edges-the welding was the
hard part as my 150A tig welder was having a little
trouble getting enough heat on the thick aluminum
and my non-cooled torch was getting real hot
Preheated the manifold in an oven to reduce warpage,
so had to handle with welding gloves.
For more clearance above the enlarged runner intakes,
a 1/4"lidspacer was made out of aluminum.
