7137 Pro-Flo XT Multi-Port EFI Intake for Chevy Small Block (1955–1986 Heads)
A long-runner, single-plane Pro-Flo XT style multi-port EFI intake manifold for Chevy small-block V8s with traditional 1955–1986 cylinder heads. It lets you convert a carbureted small block to port fuel injection, with tunnel-ram style runners feeding a log-style plenum. Power band: 1,500 to 6,500 RPM.
- Multi-port (port fuel injection) design with large, free-flowing runners
- Throttle body flange accepts up to a 90mm bore; made for a Pro-Flo XT style throttle body
- Drilled provision for an LS1-style MAP sensor, with a separate mounting bracket supplied
- Fuel rail kit included
- Port size: 1.92 in. tall × 1.14 in. wide
Before you order:
- Fits traditional SBC heads with all 12 intake bolts straight (1955–1986 style).
- Not for 1987–1995 heads with angled center bolts, and not for 1996+ Vortec 8-bolt heads.
- Injectors, throttle body and an engine management system (ECU) are not included and are needed to run the engine.
- Height is about 9.1 in. at the front and 8.2 in. at the rear, so check hood clearance.

Frequently Asked Questions
Is this a complete fuel injection kit?
No. It is the intake manifold with a fuel rail kit. You will also need injectors, a throttle body (up to 90mm) and an engine management system.
Will it fit my 1988 350?
Not if it still has its factory 1987–1995 heads with angled center bolts. For those heads, see the 300-260 multi-port EFI intake.
