So why the heavy weenie on the header manufacturer now? I thought the discussion was about TF. This thread is 3 months old. It's time you took the bull by the horns and do the research yourself. I have a handfull of stock mopar v8 engines laying around myself. Well..all of my engines are stock unfortunately. You are kind of in a good situation to be in. Do the work man. Figure it out. I'd be there to wrench with ya in a heartbeat with some stock stuff. Make it happen. Let us know. If you can prove something, you should get your money back. Do some measuring. It isn't that hard to build some comparative tools.
