The Haytalras 5026 is an Air-Gap dual-plane intake manifold with a 4150 square-bore carburetor flange for Chrysler LA and Magnum small blocks, including the 318, 340 and 360. The Air-Gap design separates the runners from the lifter valley to help keep the intake charge cooler.
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.
Which engines this fits
• LA small blocks (1967–1991): 318 (5.2L), 340 (5.6L) and 360 (5.9L) in Dodge, Plymouth and Chrysler cars and trucks
• Magnum small blocks (1992–2003): 5.2L (318) and 5.9L (360) in Dodge trucks and vans, and 1993–1998 Jeep 5.2L / 5.9L
The 5026 is set up for 340/360-style cylinder heads. On early LA heads the bolt holes are drilled about 8° off, so they need modification and socket-head bolts. It also needs a 1975-or-earlier style water neck, has no exhaust crossover or heated-choke provision, and will not accept the stock Thermo-Quad carburetor. Full details are on the 5026 product page.

Factory engine options varied by year and trim, so go by the engine in your vehicle. Engine-swapped cars are fine as long as the engine is an LA or Magnum small block.
Not the right page if you have…
• A Gen III Hemi (5.7, 6.1 SRT8, 6.4/392): different engine family; we don't make intakes for these.
• A Mopar big block (383, 400, 440): B/RB engines use a different intake; we don't make one at the moment.
• An AMC 360 in a Jeep Wagoneer, Grand Wagoneer, J-Series or Gladiator: that is an AMC engine, not a Chrysler LA. See our Jeep AMC V8 intakes.
FAQ
LA or Magnum heads?
LA engines were built from 1967 to 1991 and Magnum engines from 1992 to 2003. The 5026 is listed for both, but check the head notes above, and the cylinder-head compatibility and included hardware on the 5026 product page, before ordering.
What carburetor does it take?
A 4-barrel square-bore (4150-style) carburetor.
