And if you look at the 60ft. it was slower with the larger header, so there was another solid .6 or better in the ET with currected 60ft. I'm sure it was do to the extra HP & torque that slowed the 60ft. from traction issues off the line, Its fine with me if "some" don't listen, thats THERE loss 8).
And just to clear things up, I was running "bone stock" 906 heads & the XE284H cam at the time i made this change, I "was not" even at 500 FWHP, more like 475-480, So for you guys running all the fancy heads & bigger cams/carbs are leaving a bunch of ponies on the table, why would anyone put "fast" stuff in there cars just to sacrifice HP & torque, kind of pointless to me lol. But to each his own.
