Explorer intake swap now or later? Reply #15 – December 11, 2012, 03:25:24 PM No worries there, I got an HO upper with the throttle body from the previous owner, and I've been doing research on how to do it. One person said that the throttle shaft would swap right across, and other people say I'll have to grind off the cable mounting plate and put on the new one. I'll find out for myself. Quote Selected

Reply #17 – December 11, 2012, 11:19:29 PM Quote from: cobrajoe;404359The people I've seen talking about it on a Grand Marquis website swore that anything under .500 lift at the valve should be fine with the SO pistons. And from the cam stats I found, 1.7 ratio rockers puts me at .420 lift on the exhaust valve vs the .395 it currently is. It should work for the HO cam too, it would increase the lift from .445 to .473. Of course, I'd be smart to double check P/V clearance when installing the new heads and cam later on. AFAIK there is no issue installing 1.7 rockers on any stock cammed 5.0, I ran a set on a '86 5.0 Stang with E6 & flat top pistons...If you can get lucky and find a set of Trick Flow heads those can be used on flat top pistons, I have a set on a '86 HO short block and run the stage-1 TF cam as well...

Explorer intake swap now or later? Reply #18 – December 29, 2012, 11:50:11 PM The HO intake was a direct swap for me, with no modification at all except replacing one hose on the HO intake with a plug that was on the SO intake. My HO intake sat for a few years before I installed it, and the EGR spacer gasket dried up and blew out shortly after the swap, flooding coolant into the intake. Cleaning the mating surface of the lower intake was the worst part of the swap. The whole job took about an hour the first time, and I had it down to about 45 minutes after swapping the old intake back in and then back out. With the HO intake AND headers/H-pipe/cat-back exhaust, I noticed a quicker/snappy response when stepping on the accelerator. With the stock setup, it took a while to kind of wind up and go. It definitely feels better to drive, and not just taking off from a stop. I would say that the hour or so needed to do the swap is worth it, even without the other possible mods. Quote Selected

This was how I started with mine. Quote Selected
