# Exhaust Manifold for 1964 Corvette 327 (250hp)
Vehicle & Engine Specifications
1964 Corvette with 327 cubic inch (5.3L) engine, L75 engine code, 250hp base model
This is the entry-level small-block configuration, equipped with a single Carter AFB four-barrel carburetor and cast iron log-style exhaust manifolds.
Part Overview
The 64 Corvette 250hp model uses standard cast exhaust manifolds — not the exotic finned aluminum versions found on fuel-injected variants. This makes sourcing more straightforward, though casting variations exist depending on production date.

Fitment & Identification Notes
Before ordering: Locate the casting number stamped into the flatest face of your existing manifold. Multiple casting variations were used across the 327 family in 1964 depending on production date. Providing this casting number ensures you receive the correct part for your specific build date.
Determine your restoration standard: Whether you're building for judged concours (requiring correct date-coded castings) or as a driver rebuild (where reproduction parts are acceptable) will guide your sourcing choice.
