I reviewed the forum link that you wrote about modifying the thermostat neck to accommodate a Vortech SC and a Ford Racing intake. Excellent BTW. Sounds like we have a very similar setup. I just realized this exact issue while reviewing the installation directions for the adaptor and saw where this was going to be a problem with the FRPP intake. Would you mind if I ask you- did you just eyeball the angle or was there an exact angle for the cut to make it fit? I plan to order another Therm housing and cut it before I continue the install since my car is still currently in one piece and still drivable. The tanks have already been moved and in all the wrong places but she's drivable. Thanks in advance.
