    I just bought a 55 Chevy pickup with a locked up 350. It had been sitting outside since 97. The man that built it told me the intake manifold i IMG_20211206_155740082.jpg IMG_20211206_154103220.jpg s off a 302 z28 camaro. How can I tell? What's the value on something like that?

    That is a 69 Z/28 intake, value is dependent on condition. Pitting around the water ports and t-stat housing are usual issues. Has the center divider been modified? Get it off and cleaned up and post some pics.

    Would it hurt its value to have it bead blasted? Looks to be in great shape just dirty

    You can use glass beads, not too much pressure though. Avoid the machined surfaces as aluminum erodes easily - use Scotch Brite pads there. Clean the oil and grime off first.

    I would look into vapor blasting aka vapor honing. Really deep cleans the aluminum without messing with the surface texture. Motorcycle restoration guys have been using it for awhile and its now getting to us car folks.
