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.

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 .

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.
