Explorer intake swap, which spacer to use? Reply #15 – June 15, 2015, 07:12:46 PM Quote from: GDawg148;448898I'm doing the explorer intake swap, gt40p head swap, and I will be installing a cam. I'm also getting a double roller timing chain and gears, and replacing my water pump.With a GT40 intake, GT40/GT40P heads, and a cam a 65mm or 70mm throttle body will be fine. Either one should match up well with an Explorer/GT40 upper. Quote Selected

Explorer intake swap, which spacer to use? Reply #17 – June 16, 2015, 11:00:06 PM Just make sure to have enough exhaust. 2 1/4 minimum, 2" will be just about maxed out on that combo, so will 19# injectors. Think about 24# and MAF maybe a Cobra PCM (X3Z iirc, to make things easy, no tuning) Quote Selected
