Re: Saw these manifolds on ebay........
The name should speak for it's self.
If you are looking for replacements how could you go wrong for that price. |
Re: Saw these manifolds on ebay........
These manifolds are for sale by Dennis Moore, is this the same Dennis who wrote the book? The name on the exhaust is "GLM"? Is this Dennis' company?

Glen L Marine. I thought they were aluminum castings. If they are I was told by Glen L that the only performance gain was weight savings.

They are made by GLM Products in Monrovia,Ca.We have been selling them for about 2 years now and have not have any problems with fit or finish.You can call me if you have any questions at 504-382-2932.

Re: Saw these manifolds on ebay........
seems from what research i've done, if a manifold has the runners for the individual exhaust ports, it should help to flow better, or raise the ponies a bit.

Re: Saw these manifolds on ebay........
These are aluminum and they seem like a nicely manufactured part. I am sure they would perform much better than the old Merc log manifolds. The only thing I would consider though is that they still use a wet transfer water port joint at the riser flange. This gasketed water transfer is really "old School" and it can be a potential problem down the road if they spring an internal leak into the exhaust port. This can fill an open valve cylinder with water and this condition has grenaded a lot of motors over the years. Most of the current aftermarket performance headers and manifolds now use a dry transfer joint here now with the water routed outside between the base manifold and the riser with no chance for internal water leakage at this joint. Just something to consider when you weigh price versus value.

Ray @ Raylar Great reply, could have not said it better myself |
Re: Saw these manifolds on ebay........
you get what you pay for. Most of the time. I paid a lot (relativly) for Stainless Marine but I'd do it again because of the quality.
