Haytalras SBC intake manifolds fit 262–400 small-block Chevy V8s, from mild street engines to higher-RPM weekend builds. The range covers low-rise and high-rise dual-plane manifolds, Air-Gap dual-plane designs, single-plane race-style intakes, Vortec-head versions and EFI options.
Our V8 intake manifolds are cast and CNC-machined in our own factory, then checked for air-tightness, dimensions and finish before they are packed. Orders ship within 24 hours on business days from our warehouses in Ontario, California and Bloomingdale, Georgia.
How to choose a small block Chevy intake manifold
1. Check your cylinder heads first. Small block Chevy heads come in three intake bolt patterns: 1955–1986 heads, 1987–1995 heads (the four center bolts are angled), and 1996–2002 Vortec heads. An intake for one pattern will not bolt cleanly onto another, so this matters more than engine size. 305, 327, 350 and 400 engines share the same intake as long as the heads match.
2. Pick dual plane or single plane. A dual-plane intake gives strong low- and mid-range torque, which suits street cars and trucks. A single-plane intake moves power higher in the RPM range and suits cammed, higher-revving builds.
3. Match the carburetor flange and hood. Square-bore (4150) fits Holley-style carbs; spread-bore fits Quadrajet-style carbs. High-rise intakes need more hood clearance than low-rise.

FAQ
Will a small block Chevy intake fit my 305?
Yes, if the heads match. A 305 and a 350 use the same intake bolt pattern, so choose by head type (1955–1986, 1987–1995 or Vortec), not by displacement.
How do I tell if I have 1987–1995 heads?
On 1987-and-later heads the four center intake bolts are angled instead of straight. Our guide SBC TBI vs 4-Barrel Intake shows what to look for.
Which intake fits my C10 or square body truck?
It depends on the year: see 1975–1986 C10/K10 intake manifolds or 1987–1991 R10/V10 intake manifolds, each with a fitment table by year and engine.
Low-rise or high-rise?
Low-rise favors low-end torque and hood clearance; high-rise supports more top-end power. See Low-Rise vs High-Rise SBC Dual-Plane Intakes.
