Excellent. It would be interesting to see how that setup flows as compared to a TPIS setup.

To be honest with you I have No clue, cause the cam I have in it now, was meant to to be shifted at about 6500, which I was doing, with a stock unported TPI. I know that there is a big differnce on the top end!!!! I have plans to do more to the upper and runners, possibly taking it through on the top and bottom of each port and making them straight, making it like an oval shape, then aliminating thr gasket, and just use RTV. I will keep you guys posted on this.

 

Cool!! How is it with lower RPM TQ now, the same, better, or what?? What engine and mods do u have??
