i did have a 1968 camaro 327-4 speed purchased new in late 1967 off of the showroom floor.The engine air cleaner had 327-250 HP Turbo Fire on it.The rear end was not posi either,The engine had a Quadrajet,double hump heads,and single exhaust.It had the bumble bee front stripe..
OK here is what is confusing.My Friend Bill had a 1967 Red RS 327 4 speed with duals.His air cleaner had 327-275 HP Turb Fire.He wanted to trade the exhaust out and we did.He wanted to run me,and we did Two times.First was from dead stop and I left him sitting several cars back.The second run he wanted to do it from around thirty MPH,as he said he was not getting any traction,and I left him in the dust again.I know it was a long time ago also.I do remember it like it was yesterday.After searching lots of sights I am still confused about the Air Cleaner on my Engine.Was it possible for GM to accidentally install the wrong Air Cleaner on my Engine,that is what I am asuming.I can not find anything on 250 HP in a 1968 Camaro,only on larger Vehicles.This had to be the L30 engine is all I can find any where on here.Thanks for all the answers I can get.

 

hay ken welcome to the forum. I moved your thread to 1st gen section for you. ask gm is more for new models and is not very active. you should get more response here. we got some pretty good 1st gen guys on here.

 

Thanks much.

 

I have never head of a miss labeling on any Camaro air cleaner. If this was something that happened there would be information on the net about it. At some point these cars would have made it to a car show and the factory mistake would have been documented. Casting number and casted in dates can help solve the mystery.

The show circuit is very detailed about deviation from the norm. There are tons of notes from the 72 strike year. GM did a bunch a stuff to get cars out the door even in low volume. This included olds parts on chevy's external trim pcs left over for 71. Keep in mind in a real numbers car show if the dial on your radio is not the right shade of orange your car is considered not correct. All the casting codes are checked. I have seen cars dinged for a wiper motor that was only used half a year and based on the date of manufacture the date the car was built in the other half of the year. I always thought this was ridicules. Heck that wiper motor could have been changed at the dealer before the car was picked up if it was found during the new car inspection as a problem. The owner of the car would never know. not to mention the mistakes the factory made.

Don't forget that the camaro air clean is a camaro only item due to the height. I assume the top plate only is off a different car. There are some issues if you believe that this car is in its original state. The L30 275 would be the only 327 to have had double hump heads on it, but a L30/4 speed car would have come stock with a 12 bolt rear. This is why the L30/ 4-speed is nicknamed the poor man's SS. If you got the L30 and the 4 speed you ended up with a Muncie 4 speed and the 12 bolt rear. GM engineers did not believe that the Saganaw/ 10 bolt would not hold up to the 275 HP and you got the upgrades at a fraction of the cost of the SS Package.

Just a FYI the double hump heads was a hugely popular upgrade in the 70-80s to the 327. A set of 2.02 small camber heads would turn you 210 HP 327 to close to 300 hp. These heads did become hard to find once the circle track guys started buying them up.

 

Thanks Gorn.

 

I am searching high and low to find this 1968 Camaro,with no luck so far.I know what bank Financed it and it was in my fathers name.I will keep looking I don't have any paper work at all.I know the Texas DMV has it but it has to be some kind of Judge based hire to maybe get it for the vin,etc.

 

Interesting,I looked in my 1967 Motors Auto Repair Manual and in Camaro they show three different 327s but none are 250 hp.
They are 210 275 and 350 hp,I did not find a 250hp 327 in any other '67 cars either.
I did find a 250 hp 327 in '64 & '65 Chevelles and Novas but by '66 it was gone.
Motors could have gotten it wrong possibly but you'd think the 250 hp would have shown up in one of the other '67 models if it was there.
I found the 250hp 327 as far back as '62 in a Corvette but nothing after '65 in any car.
As for running your friend,seems odd he wanted to trade his dual exhaust for your single,he would have lost hp and you should have gained hp.
Aside from that there's a lot of things that come into play including the drivers,maybe you ran your car harder with more rpms and maybe you had a close ratio trans and him a wide ratio or maybe you had lower rear end gears which makes a big difference in acceleration.

 

If the car is not restored there should be a build sheet under the rear seat or above the gas tank. It will give you all the options the car originally sold with.

 

IIRC "double hump" heads were 2 version. The 1.9x/1.5x or 2.02/1.60 ones with the later being the preferred ones and I assume the ones used on the highest HP 327

My understanding is the 327 available in 1st gens was the 210hp 2 brl version and the 275 hp 4 brl version

Maybe the air cleaner lid was changed on the car referenced with the 250 hp 327

 

Chances are you just had one that ran well
I had the same thing
A 69 with a 255 hp 350 turbo fire
Ran like a raped ape and people asked me if I was sure it was not a Z-28
Enjoy the fast ones when you find them
Just got a 68 and not so sure about this one yet
