Life got in the way.
My wife told me she was pregnant 2 weeks after the Schumscher Tri Y headers came.
Sold the whole project 2 weeks later. My research Indicated the tri y headers were a decent fit, Good for street/strip, producing lots If torque and great mid range, but left some horsepower on the table in the Upper range. A guy i corresponded with said that from 2500-5500 said that the headers made made a big difference and the engine pulled like a freight train in mid range.
