marine manifolds for cadillac 346 V8 engine wanted

You may want to contact OSCO Motors, Hatfield, PA (Northern suberb of Philadelphia).

Contact: Tom Cooper, President.

Their sole existence is aftermarket marine manifolds and retain a "very experienced" staff.

Sorry that I can not provide the phone number, or, other pertinent data this evening.

Go to Osco Motors on the web and I am quite certain you will receive a direction...

Regards, Peter J.
