Sam, I know this may be a silly question, and forgive me if the explaination got lost in the sea of
obscuring this thread...
But what exactly are the differences between the VR38 manifold and the VQ37 manifold? Is it purely the material/design/legths of runners, or are there a series of reasons why this will be a much better improvement?
Just curious how this one say stacks up vs the stock manifold and say the Motordyne manifold as well??
