The Edelbrock Pro‑Flo XT EFI intake manifold for Chrysler 413–440 big‑block engines is engineered with a large plenum and long tapered runners to expand horsepower and torque across 1,500–7,000 rpm. It features a 90mm throttle bore and was shown to produce about 20 more horsepower than Edelbrock's reference manifold at 5,500 rpm. The manifold accepts Pro‑Flo XT throttle bodies and compatible fuel rails.
