1987 Chevrolet V10 - LT Swap

The 3rd Generation C10 was a clean-sheet redesign that lasted GM 15 years. Like its predecessor, the Square-Body C10 featured optional small and big-block V8s that make this one of the most versatile bases for your build. Whether you're autocrossing, drag racing, or just cruising, the C10 can get it done. Whether you want to perk up that old small- or big-block or retrofit a late-model GM LS or LT engine, Holley has the parts to get it done.
