The Edelbrock Performer Buick/GM V6 intake manifold is designed for 1979 and later 231/252 c.i.d. Buick V6 engines with late‑model cylinder heads and is not compatible with pre‑1979 blocks. It is not equipped for EGR and is incompatible with certain C‑3 and C‑4 electronic fuel management systems, making it a targeted choice for later‑model street installations where those limitations are acceptable.
