Re: Higher value 69 Chevelle COPO 427 or L-78/L89?
 

The reason I say Chevy lost money on the COPO cars is because of the engineering costs. Engineering costs are very high but when divided over 500,000 cars it is not that much per unit. With only about 1000 hi po COPO cars built in 1969 there was no economy of scale.

There's still no substitute for cubic inches..plus I only weigh 160 lbs. so I still have the edge ! Plus Mr 70 is from the south side...they never figured out how to drive down there.

I have personally felt the power of the iron 427 and the ZL-1 in a Camaro. I guess the car that really impressed me the most in the last couple of years was the 68 NOVA that won the MCR stock appearing shootouts. This car should leave no doubt concerning the performance potential of a properly tuned 396 car.

.....if it is a 396 car!

The 1969 L78 and the L72 were very similar engines and shared many parts. From memory I believe the crank, cam, 840 heads, Holley, dist, intake and exhaust manifolds were the same part numbers. The L72 just had 31 more cu in. Chevy originally rated it at 450hp then reduced it to 425hp with no modifications.

What about the 69 SS 396 Orange post car with a L-89 that's in Floyd Garretts museum. I am told there was only 6 of those made. Would it bring COPO money.

COPO is a magic name,this name open many doors, L89 is just and addon,
and COPO 427-425 HP is comparable with a Mopar Hemi 426-425 HP
Chevelle SS396(375 HP) is not comparable with a B Body Mopar Hemi.

Re: Higher value 69 Chevelle COPO 427 or L-78/L89?
 

In STOCK trim, the 2 engines are probably close to 1hp per cubic inch, which gives the edge to the L-72, by about 30hp. The weight savings of the L-89 is probably around 150(?) pounds. I would rather have the 30hp https://www.yenko.net/ubb/smilies/images/icons/smile.gif.

And like Pete said, the 396 Nova that was mentioned earlier probably shouldn't be used as a reference...I'm thinking it's not quite stock.;)

Hi all,

I don't know if this is cool but I am posting to bring this old Topic back to the active posts.

Great stuff in here, right up my alley.

IMHO I am with MR70 and Mickey Hale, L89 is damn sexy, and win or lose I would love to chase down a COPO with one some day.

Ryan,

Trust me, You"ll never catch a COPO Chevelle with an L89 Chevelle. Two different animals.

I am a huge fan of both. But, if someone said you had to pick one..... I would choose a COPO Chevelle all day.
