The Edelbrock Street Tunnel Ram 2‑O dual‑quad intake manifold is built for big‑block Chevy V8s and targets top‑end power in pro‑street or marine installs. It fits 396–502 ci big‑block Chevy engines with large oval‑port heads (1975 and earlier) and pairs well with Performer RPM cam/kit #7162. The design favors high‑RPM breathing and is intended where low‑end torque is secondary to peak power.
