I've got one I just wanted to see if my friends measurements were close to what everyone else running that set up had. Hes the one doing the install for me.

He ended up with 7.350 on the intake side he didn't do the exhaust yet. Hes going to and let me know. He said the stock 7.4 held the valve open slightly. That was with LS7 lifters to.
