2021 High-Rise Dual Plane Intake for Chevy Small Block (1955–1995)
A high-rise, dual-plane intake manifold for Chevy small-block V8s, 262 to 400 cu. in. It sits 0.70 in. taller than our 2001 for longer, straighter runners and more top-end power, while keeping dual-plane street manners. Power band: 1,500 to 6,500 RPM, a good match for a cammed 350.
- High-rise dual-plane design, 4.65 in. height
- 4150-style square-bore 4-barrel carburetor flange
- Operating range: 1,500–6,500 RPM
- Port size 1.23 × 1.99 in.; provision for an oil fill tube
- Accepts late-model water neck, A/C, alternator and HEI
Before you order:
- Fits 1955–1986 heads and 1987–1995 305 / 350 heads with angled center bolts. Not for 1996+ Vortec heads.
- Non-EGR, for off-road / racing use; not legal on pollution-controlled vehicles.

Frequently Asked Questions
Low-rise or high-rise?
A low-rise (like the 2701) favors low-end torque and hood clearance; the 2021 high-rise suits a modified engine that revs higher. Read our low-rise vs high-rise guide.
