High 69 Z-28 cross ram prices coming to an end??

[Stuart Adams]

I never in my post said factory performance parts aern't cool. I love performance enhancement. Were these manifolds performance enhancers, I've read were they were a pain in the butt to run and never worked as should. Nothing against what people put on cars but these manifolds seem less about performance than looks.
I never doubted the way a person restores their car, just looking for clarification as to if these were factory or dealer installed. Good luck with your project.
