#312-P4529463 (413/426W/440)
Great for Super Stock, bracket, and general high-performance, these single plane manifolds are for standard (no modification required) or Stage IV/V cylinder heads and 4-bbl carbs.
#312-5249358 (4-barrel carbs)
#312-4876127 (4500 Dominator® carbs)
These single plane race manifolds are for "RB" engines with Stage VI cylinder heads.
#312-P5007381 (1992-Up Magnum 5.2L/5.9L)
This dual plane manifold for 4-barrel carbs enables the conversion of EFI to carburetion.
#312-P4529117 (361/383/400) *pictured above
#312-P4529118 (413/426W/440)
Great for Super Stock, bracket, and general high-performance, these dual plane manifolds are
for standard heads (no modification required) or Stage IV or V cylinder heads and 4-barrel carbs.
They are similar to stock manifolds but with larger cross-sectional runners for increased power,
and their heat crossovers make them ideal for dual purpose applications.
