Vintage manifolds
I need a little info regarding manifolds.
As I posted in a previous post, my 454/425HP motors have old 3" log manifolds right now.
I have one friend who has a stock set of manifolds from a early 90's 454/365HP, they are the stock merc 4" cast iron ones.
I have another friend who has a set of manifolds off a early 80's scarab 38. He says they are mercs PRE-Gil performance manifolds. They are cast iron, but he says they have individual runners.
Im sure either one of these manifold styles are better than what I have now, but Id like more info regarding the "pre-Gil" merc performance manifolds from the early 80's. Thanks

Re: Vintage manifolds
personally a wont put used manifolds on a boat, If a customer asks me to I ask them to find someone else to put them on
I do it right or I wont do it at all ( just my policy )

Re: Vintage manifolds
Those early Merc manifolds were prone to reversion and failure. The 420's used them for a couple of years. The 425's used Gil manifolds. They would be a good choice.

What if the manifold is off an engine (your own) your replacing/rebuilding?
