You know, the best thing about these forums is how many have such different opinions. That's what makes it so fun. The way some don't like the copper look and others do. There are ones who want bone stock, the way it came new. There are some who want or get creative.
Some get annoyed when others hijack a post, me, I enjoy all the input as it still generally pertains to questions asked, and, answered.
Me, I'm going with manifold heat. I kinda like the copper look. I am going to have one input going to the bottom plate from one Williams header. And the other line I am going to run a little longer and tap into a 45degree welded bung about 1foot below the collector into the exhaust following this theory.
Flow: exhaust gas will always flow from high pressure to low pressure. Heat (hot air, conduction etc.) will always flow from high temperature to low. As posted by panic.
In this fashion I hope to achieve an in and out heat from the exhaust . I will post pics when I am done. I have the dual carbs from Tom, the Offy intake, Williams headers and the dual exhaust kit for those headers. I should be done sometime around May 5th. Including my swapping out my 216 for a 235. Gettin excited!
Sadly, the 216 is awesome, just cracked block and leaking coolant. Even after good JB weld fix. Phil...
