Mastodon Chevy Small Block Aluminium LWP 2 Groove Crankshaft Pulley

Aluminum 2-groove crankshaft pulley for Small Block Chevy with the LWP (Long Water Pump) accessory drive — the most common pre-1969 SBC arrangement. The 2-groove design supports both alternator and a second accessory (typically air conditioning or power steering) on a serpentine-belt-equivalent V-belt setup.

Lightweight aluminum construction reduces rotating mass at the crank for crisper throttle response.
