I would like to toss a set of alum manifolds on my boat next year, I know I won't gain much HP, but would like to shed some weight and a better sound. Just crunching some numbers and wondering I'd my stockers are worth anything. Not sure what set I would like to go with so I'm open to opinions.

Thanks
Mike

I'm sure they are because it's an item that does need to be replaced on these engines eventually. So I'm sure somebody is in the market for them.

I don't think the 377's have different manifolds than a 305/350

Anyone have any idea what they would be worth?
