Engine is FWC LM318 with Carter 4bbl AFB carby.
My intake manifold is flaking chunks of iron around the port side thermo device that operates the choke. Intake manifold needs to be replaced. I understand an Edelbrock Performer aluminium manifold will work. I also have the opportunity to acquire an intake manifold from a FWC 360 engine. Will the 360 intake manifold fit my 318?
Finally my manifolds and risers need to be replaced. Does anyone have experience with including the manifolds and risers in the FWC loop? I guess you need to increase the heateschanger size. Any ideas?
regards,
Scott. |

Yes. They are the same.
..."Finally my manifolds and risers need to be replaced. Does anyone have experience with including the manifolds and risers in the FWC loop?"
THe factory included the manifolds only, but you MIGHT get away includfing the risers as well. You'd need a block off plate at the riser/ elbow joint.

PS: You could not do it with those god-awful swivel elbows. |

? on the aluminium manifold for a LM318 will there be a problum with the carb.sitting flat on the edelbrock.There is a 6deg. slope on marine manafolds to compensate fuel with the floats.
Thank you George |

Also, don't use an aluminum manifold on a raw water cooled motor. Electrolysis will wreck it.

Thak you. I have sourced a near new intake manifold on a 360 marine engine that is being wrecked.
