As I mentioned in another post we recently found our original intake manifold on our 403 has the crack starting and is about halfway through. Based on what I read here, it appears the only options for a new intake are aluminum, made by Rockwell and Edelbrock. I called Cinnabar today and they have the Edelbrock aluminum manifold and include the "turkey tray" with it as well. They mentioned it is raised about 3/8" above where the OEM one is so I will have to check to make sure we are good (they mentioned that it should be OK as long as the body pads are in good shape).

Going with aluminum, is there any downside or anything to watch out for? Are the aluminum ones less prone to crack like the original? I thought I had read once the green ethylene glycol antifreeze could potentially eat away aluminum but is that really an issue? Any other plusses or minuses? Maybe we're stuck going with this as I'm guessing finding a cast iron manifold means going with a used one... and I'd rather do this once and do it right and not have to worry about it ever again.

Thanks much, in advance....,
