| MerCruiser V8 454 7.4L and 502 8.2L Chevy Marine Exhaust Manifolds 1983 and newer |
The manifold above is known as the "Center Riser" manifold. It
replaced the MerCruiser "LOG" manifold for the 1983 model
year. The log style manifold has the riser at the back of the
manifold.
The Moore Performance manifolds are an exact replacement for
the 1983 and newer 454 502 MerCruiser Big Block Chevy
manifolds. The external dimensions are identical with all holes
drilled and tapped like the original manifolds.
These manifolds are available in either cast iron or aluminum.
Both the aluminum and the cast iron manifolds have identical
dimensions. The aluminum manifolds are considerably lighter
(20 pounds versus 49 pounds).

Each manifold includes a
stainless steel manifold-to-head
gasket, a stainless steel
manifold-to-riser gasket, and a
