Mastodon Small Block Chevy – Big Block Chevy Swivel 90 Degree Aluminium Water Neck – Polished

Polished aluminum 90-degree swivel water neck for Small Block Chevy and Big Block Chevy. The 360-degree swivel design lets you rotate the outlet to any clock position — vital when an engine swap, custom firewall, or relocated radiator means the upper rad hose doesn't line up with the factory water-neck angle.

Two-piece aluminum construction with O-ring seal between the halves and chrome-plated socket-head cap screws. Bright polished finish suits any chromed/polished engine bay.
