1989 US Marine 454 Engine exhaust manifold source

[jgreggriffin]

Where can I find exhaust manifolds for US Marine 454? In a 1989 Bayliner 3485 Avanti. Fresh water cooled. Will Crusader exhaust manifolds work on this engine?

Howdy

About any BBC exhaust manifolds will bolt to the 454, the issue is if they will also connect to your exhaust system. If you can post a pic of what you have, maybe we can help

Where they dump out, 'n where the accessory holes are is another story,...
