The guy on the other board "Notorious" is WRONG...he says that the F-bodies got the aluminum heads...that is completely wrong...the Y-bodies (VETTES) had the aluminum heads. I know what L98's look like...I just pulled my original '92 L98 from my Z last year and had a 383 built. The engine in the picture above is most definitely a 305 TPI NOT a 350. LT1's first appeared in the Vette's in '92 and the first time in F-bodies in '93. '87 is "considered" the forst year for the 350 L98 engine and they were available in the Iroc's or Z28's til '92. You can even tell that engine is a 305 by the accessory mounting....and even just by looking at it. Check the vin and the casting on the block and you'll see.

I've seen 2 of them before. One was a 87iroc for sale. The idiot said it was stock.

DTA - Don't Trust Anyone.

 

Thirdgens have been out so long now, some people may not even be trying to fool you since god only knows how many people have modified it and sold it already. The 4th owner may have believed owner #3 when he told him it was all stock and then he tries to pass it off as the same.

 

That's is the stock 85 305 TPI... 350 tpi was not put in the camaro till 86. Witch is the only year there was a 350 TPI "without" centerbolt heads. And the LT1 didn't come in a camaro till 93, and 92 in the big brother "The Vette".

 

Yep. No aluminum heads for the 3rd gens. I found a great old "Motor Week" video on the 87 Iroc on the web and they confirmed that the aluminum heads from the Vette had a hood clearance problem on the IROC. I think it was probably because GM didn't want the IROC to be faster than the heavier Vette. Probably the reason a 5 or 6 speed manual was never inroduced.

 

The iron heads are why the "L98" in F bodies actually got the B2L RPO code instead of L98.

 

actually.. the 350 didn't show up until 87. Therefore, there were NO 350 3rd gens with perimeter bolt valve covers.

 

1987 through 1992 L98 f-bodies did indeed get the L98 code on their RPO stickers. The B2L package included the L98 engine. This has been discussed and proven over at thirdgen.org (including many photos of rpo stickers showing both L98 and B2L).

The original Corvette L98 (introduced in model year 1985) had iron heads.

Halfway through model year 1986, aluminum heads were introduced on the either the Corvette convertibles or coupes (can't recall which one though I tend to believe it was the 'verts).

In model year 1987, all Corvettes went to aluminum heads.

First of all the 350 was only an engine optioned for the 87-90 Irocz & the 91-92 Z28s. & of course the 87-92 T/A, GTA & Forumla

 

Yeah right then you are not a ture camaro man. There where 50 L98's made in 86. And they had perimeter bolt valve covers....

Yes, you got to love those 50 1986 Camaros with the 350 engine that went to the Big Crusher and are still remember to this day. They also had a name: TEST MULES.... Which means they were not sold to the public.

 

prototype/test mule cars will never be listed in production figures...........

 

There you are wrong. Not all the time but since we all know there were 50 Camaros produced with the 350 in 86 it is also a known fact by everyone that they did not make it to public sale. The guy that did the reseach on this just noted it because they were test mules.

also you cant tell a 350 from a 305 from the look of the engine. There is also NO VIN code for the 350s made in 86. They were crushed or destroyed.

 

i never said they were in production , just made....

 

Well I was TRYING to simplify things for the origonal poster.

He will NEVER see a STOCK l98 in a third gen with perimeter bolt valve covers.

That is what I was TRYING to get at!
