I was trolling the interwebs and found a 71 455 engine sold as a core,i happened to notice it has a Z manifold rh and possibly W on the left, also both valve covers are of the notched design,my guess it's from a Cutlass.My question is what are the manifold and valve covers worth? Nick

 

Manifolds are repop for about 300, so pitted originals w good threads maybe 2-250.

VC w no dents and clean maybe 150 on a good day avg drvr shape 75-100.

Core 455 250-500 depending on location and what's included w it

 

Here are some pics if it is still available this weekend i will go look at it thanks for the info.Nick
