1968 NF2 ?

[mr396]

I just noticed in my 68 aim under NF2,It states DWG 5-22-68,REL 6-22.Does this mean there wasn't any NF2 camaros built before 6-22-68? http://www.yenko.net/ubbthreads/images/graemlins/dunno.gif http://i11.photobucket.com/albums/a180/mr396/aim.jpg

I too would like to know the answer to this!

Sure they were. They were called 1967 Camaros. In 1967 the RPO code was N61 for that exhaust system. N61 (67) and NF2 (68) consisted of the same exhaust sytem just a different year.

I believe that the reason that the sheet is dated for a 6-3 release is because that is when the N10 was cancelled so the NF2 would have taken over as the only dual exhaust for the low hp V8's.
NF2 was available all year long as the exhaust for the bigblocks.

[Rick H]

N10 was still available along with NF2 in 1968. They were two different systems.

Rick,
The assembly manual shows the N10 as cancelled as of 6-3-68, is this incorrect?

Ok... so i have my 04A built 68 Camaro...it had the dual exaust as the brackets and muffler is still under it (looks like swiss cheses!! lol) but what RPO code was origionally on my build sheet? N10 or NF2... judging by the above post it was N10... but I may be wrong.

[Rick H]

I am quite sure it was not cancelled. N10 was an option found on the low horsepower cars. The NF2 was for any of the higher horsepower cars such as the 295hp 350 and up including the 375hp 396.

A little over 4400 cars were equiped in 1968 with N10 exhaust and a little over 9000 on the NF2 so that doesn't sound like it was cancelled.

Also to note is N10 was still an available RPO in 1969 along with NC8 Chambered (for a while).

Ok Rick..my 68 has an L30 in it.. which was lower than the 295hp 350 and up u say got the NF2. So that means if my car had factory dual exaust it was of the N10 version? what are the distinguishing differences in the N10 and the NF2.. were the pipe diameters different? different mufflers?

[Rick H]

Your car would have the 2" pipes with the muffler being the same 2" input and output. The other systems would be the 2 1/4" inch.

If it was cancelled 6-3-68 then it would have only been 2 months of production... so the production figures could be correct.

N10 is the dual exhaust, only available with the 327, available the whole year. Included with the SS's and Z28's (hence not an option).

NF2 replaced N61 in 1968. It was available the whole year. I'm not the expert on it, but I recall it included resonators for a different sound. It basically modified the dual exhaust.

Not sure if you could get NF2 *and* N10 on a 327 car.

[thesupernova86]

So now my car could have either came with N10 or NF2? correct?

mr396.. sorry i hijacked your post... whats your situation looking like? look like you got a oretty good topic stirred up here!

[Kurt S]

I've never seen a 327 (LF7 or L30) documented with NF2. Several 327 cars with N10.
I don't have 68 ordering info handy to dig into the details of what engines NF2 was available with, but I wouldn't assume it was available on 327's just yet...

[thesupernova86]

Ill just stick with the N10 idea for now until i find proof otherwise

[Kurt S]

Argh. I messed up.
We know of 2 documented L30 cars with NF2. And it's now clearer to me that a car had either N10 or NF2.

Rich Fields adds:
Parts manual covers both systems in 68, and both applied to 327 or 350. The 327 also used the same pipe diameter as the 350.
Z28 had the NF2 equivalent system, but different front pipes (not sure why, the rest of the system was the same.)
