Well, not that this has anything to do with Transmissions, but the LB8 is just a port injected V6... Its not crossfire or anything like that... Just a plain MPFI V6... 2.8L of course...

The "Crossfire" motor was a V8 for one. Also, it was a Dual TBI engine.. And yes, it was gone after '83..

no, it looks nothing like the MPFI 2.8 i had in an 88 S/E, nothing at all similar cept for block and heads maybe, even valve covers are different, in this 87 they are smooth gray steel, wierd looking, the 88 MPFI ones were different

this isnt the same setup, at all, way different,
the 88 MPFI didnt have x shaped intake like this 87 does



i have no digicam sorry, i wish though

No V6's were put in Z28's... I've never seen a Z28 with a V6.... Z28's up to '87 at least had an LG4 V8...

It's not a Z28.

It's not factory; at least not for one of these cars.

LB8 is the usual 6-cyl RPO code. No mystery there.

Sounds aftermarket to me.

Factory "CrossFire " was on V8s, and consisted of 2 TBI units; one on the left feeding the right bank, and one on the right feeding the left bank. 83 was its last year. It never came on 6-cyls. In those days, the 6-cyl motors were carbed.

The "dual snorkel" air intake was used on both the TPI V8s, and the MPFI 6-cyls. Again, nothing unusual there.

Sounds like somebody installed an aftermarket or other-model intake manifold. There's a certain number of such things in the marketplace; since it fits S trucks as well. Anybody could cast a piece of aluminum and include the word "Crossfire" on it; no wires or hoses would necessarily have to be moved.

Pics are worth 1000 arguments. Maybe more.

ok my bad, i stand corrected,
yep its not crossfire i was imagining that it said crossfire,
but it doesnt,
the x shaped intake setup really threw me off,
so youre right 83 was last for that system yep, i learned something again, more to learn yet for sure



anyways why did the 88 s/e i had have normal non-x shaped MPFI intake on its 2.8 when this 87 maro out here has this funky x shaped intake setup ?

this 87 2.8 doesnt look like that last engine pic either, not the intake setup anyways, doesnt look anything like what was in the 88 either, at all

apparently 2.8L had a billion different intake and/or injection systems,

hmm..


so this z28 is not really a z28 ? it has red blue emblem on front nose bumper cover, and says camaro on dash emblem pass side face of dash, all black interior everywhere, cloth interior and seats



what is going on with this car ?

and why does the 2.8 in it look nothing like the usual 2.8 ?

what does the vin code say this car is ?


thanks

Somebody stuck some stickers and an aftermarket or other-model intake manifold on a base-model 6-cyl Camaro. The sticker thing especially is real common.

The VIN cose says the car has a 6-cyl. That means it says it's a base model Camaro, not a Z28.

This is not that hard to figure out. We're not talking rocket science here.

Could be.... idiots have been known to do things even more idioitic than that

Could have been a rocket scientist or a brain surgeon for that matter

It's a handful of screws and some stuff you can find in the junkyard

Why is this so hard for you to understand?

Here is a real tough one, look in your console and check the RPO codes, if one says Z28 then guess what, it's a Z28. Also check the VIN # on the RPO sheet against the one on the dash.


At least you got some cool stickers.

I doubt its a "fake Z28". Its certainly not a Z28, but keep in mind, they did put GFX on some Sport Coupe V6 models..... I believe late 87-88.

im not a rocket scientist or anything but i figure that a car thats not a Z28 but is badged as such is prooooooobably a fake z28

just a hunch

it definitely has z28 gfx pieces and such,

what hood was used on 87 z28s ? smooth one right ?

dash badge be one that says CAMARO only ?
hood emblem on center front is red white blue ?
nothing on bumper cover anywhere in rear


no it doesnt have RPO code Z28 listed nope

thanks

hehe

i dunno

i just like calling it a fake Z


why couldnt it be called such

did 85 up Z's have different nose/lights than base models ? or were they all the same ? i know 82 84 the Z's had extra pieces on the nise down low, had a different look than the bases

but 85 up ?

this 87 outhere has nothing extra below the bumper cover and has plain boring looking parking lamps,

thanks
