This may not yet be technical enough but....what if someone changed exhaust to a 3x2 i.e. D&D or something to free up the single stock pipe on the left side...reconfigure the pipe (even slightly larger diameter) as a cooling tube with copper tubing and brass fins and exterior louvers to guide air flow into the pipe..allowing a reduction in size (width) of the stock radiator?...this is a far cry from real details but I think the idea could work...are there any of you wizards out there that might see this as possible? Maybe I will revisit this post in the morning before tequila hour....
