intake manifold hi-rise aluminum natural dual square bore chrysler dodge 331 354 392 hemi each

Weiand's single plane Hi-Rise intake manifolds are designed for early Mopar V8s, including the smaller Hemis. There's a single 4-barrel version for early small blocks that takes a square-mount carb and has a broad power band stretching from idle to 6,000 rpm. There's also an inline dual 4-barrel setup for the classic early Hemis, which takes carbs with a square mounting flange and has a wide, 2,000 rpm to 6,800 rpm power band. Throttle linkage fabrication is required.
