This TSP distributor is engineered as a direct-replacement unit for the factory computer-controlled distributor used in GM's TBI and TPI EFI V8 applications from 1987 through 1995 — restoring accurate ECM signal control and reliable spark delivery without reprogramming or additional ignition modules.\u003c\/p\u003e\n\u003cp\u003eBuilt around a magnetic pick-up trigger and a male terminal connector, this distributor integrates directly with the factory EFI wiring harness and ECM on compatible non-Vortec applications. Computer-controlled advance means the ECM manages ignition timing — no mechanical or vacuum advance tuning is required. The machined aluminum housing and steel gear are built for long-term durability in daily-driven trucks and working vehicles.\u003c\/p\u003e\n\u003cp\u003eNo ignition box is required. An external coil is needed and is not included. Verify distributor gear material compatibility with your camshaft before installation — the steel gear is most compatible with cast iron hydraulic and solid flat-tappet camshafts.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eApplications\u003c\/strong\u003e\u003cbr\u003eCompatible with Chevrolet Small Block V8 Gen.

For 1996–1997, application is limited to one-ton G and P series vans only — not compatible with 1996–1997 Vortec-equipped trucks or SUVs.
