Buick SB 215-350 V8 HEI Distributor
The TSP HEI Distributor for the Buick small block V8 is a self-contained large-cap HEI ignition upgrade covering the full Buick small block family — 215 CID (3.5L), 300 CID (4.9L), 340 CID (5.6L), and 350 CID (5.7L) — in carbureted applications. The integrated HEI design combines the ignition coil, ignition module, cap, and rotor into a single unit, connecting to a single 12-volt source with no external coil, ignition box, or condenser required.
The 65,000-volt internal HEI coil delivers substantially stronger spark than a factory points-style distributor, supporting easier cold starts, cleaner idle quality, and more consistent ignition performance across the full RPM range. A magnetic pickup trigger replaces the mechanical points contact and requires no routine maintenance. Both mechanical and vacuum advance are included, with a vacuum advance adjustment tool shipped with the distributor for advance curve tuning.
This distributor also fits the 1970–1974 Range Rover equipped with the Rover 3.5L V8 — which shares its foundational architecture with the Buick 215 aluminum V8, making this a direct ignition upgrade path for early Range Rover carbureted applications.
The Buick Small Block V8 Family — What This Distributor Covers
The Buick small block V8 is a distinct engine family that spans four displacements across several decades and two continents. The 215 CID aluminum V8 was introduced in 1961 and used in the Buick Special and Skylark before Rover purchased the design in 1965 and continued producing it as the 3.5L Rover V8. Buick subsequently grew the small block architecture through the 300 CID (1964–1965), 340 CID (1966–1967), and 350 CID (1968–1979), used across the Skylark, GS, Century, Apollo, LeSabre, and Riviera. Despite spanning different displacements and eras, all four share compatible distributor architecture — making this one distributor the right upgrade across the full Buick small block family, with one important caveat on the smaller displacements.
Performance Benefit
Replacing a worn or points-style distributor on any Buick small block V8 with an HEI unit delivers immediate improvements in starting reliability, idle quality, and part-throttle drivability. The 65,000-volt internal HEI coil fires spark plugs more reliably than a factory points setup, and the magnetic pickup trigger holds timing accurately without the wear and drift that accumulates in mechanical points contact over time. Both mechanical and vacuum advance are included, and the vacuum advance adjustment tool allows the vacuum curve to be tuned for your engine combination and driving conditions.
