1963-66 A-Body B/RB Kit
Here's a swap for the truly adventurous — put a Big Block 383, 400 or 440 engine in your early A-Body! High performance, high strength polyurethane spool mounts fit in place of your S6 or small block V8 biscuit mounts. Kit includes powder-coated brackets, poly spool inserts and grade 8 bolts.
NOTE: Requires custom headers/exhaust.
