Hey guys i have a 95 with a pi top end swap, i had a 96,97 upper intake plenum and never had a problem with it, i pulled the motor out to freshen it up, and i purchased an aftermarket professional products power flow upper intake and throttle body and with the hood closed, the throttle is completely stuck close hits right on bend on rear of hood, just curious if anyone else had ever had this issue? Any help would be awesome
Thanks Matt

The 96/97 hoods were designed with a 'bulge' to allow additional clearance due to the taller intake setup. Your options are either a 96/97 hood conversion, aftermarket cowl hood conversion, or remove some of the thickness of the stock hood by cutting out the blanket/support bracing.

thanks for the fast reply, how come the 96/97 factory plenum throttle body fit fine?

My guess is the throttle arm where the spring and cable attaches to is either moved slightly or is of different dimensions compared to the stock 96/97 setup.

That aftermarket upper plenum could be taller than the stock MN-12 plenum as well (like the Crown Vic one's are).

Look at the difference (TBird on the left, Crown Vic on right):

BTW, if the motor mount fails, it also stuffs the linkage against the hood, WFO.

You were warned, lol.

well the mounts didnt look in bad shape when i had the motor out, it looks as if this aftermarket intake is about half an inch or so taller than the stock set up, from just comparing them, i made a couple slits in the underblanket and notched it out to clear this set up, it would make since it was taller since its a much larger throttle body upper intake than the factory one, and you could tell the factory one had been rubbing the heat blanket on the bottom of the hood.

Dude; PMs should not be like this:

Intake fitment problem
so have u actually seen that intake problem before, mine was was just barely not cleaning it needed about and inch to clear.​

That's barely comprehensible; I had to search for this thread to know what it was about.

I've seen all kinds of interference problems, on various cars.

I've had a motor mount fail, stuffing the throttle wide open. Not recommended.
On our cars, almost Nothing fits under a stock hood; the running joke on this board is "Will it fit under a stock hood?"

No. No it won't. Usually. :)

Holes have been cut, Scoops made, various hoods are available.

My dohc build will stick out ~2", I saw a shaker hood I like; maybe I'll go that route. :)

Ditch the '95 hood...there's a reason why the '96-'97's have the bulge in the center.

Bumper change absolutely not required.
Yeah I guess Trunk Monkeys is like that. Regardless, hole has been cut, no use in wasting time and money on a different hood and headlights when they are in good condition.

Yeah, looks. The bulge in the 96/7 hood's additional height is most prominent above the alternator, not the TB/Plenum.

I can see where the hood bracing can be a problem with aftermarket parts though, but that's nothing a BFH couldn't solve:tongue:

:D


I just used the timer button and closed the hood. I set the camera on the battery in the first pic, placed it sideways on the shock tower for the second, valve cover for the third and on top of the fuel lines for the fourth. Needed to start figuring out just how much taller the Mach 1 motor will be under there:leftright
