Yes, you obviously did, but I also mentioned way back about buying a smaller intake because I suspected this Indy was designed for a bigger program than mine imo. I think I remember my idea getting poo pooped by a few here. Like you said before, combination and I always agree with that, but compression and velocity matter as well. I probably made this intake worse for my combo with the bigger plenum. I wont spend $1700 on it. I can get a new intake for about $500. Gonna show these heads to sanchez tomorrow. I think I'll take the intake with me.
