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.

• Operating range: 1,500–6,500 RPM

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.
