351w EFI Clearance for stock hood

[mattt]

I measured both manifolds, these are quick rough measurements. The flange where the throttle body bolts up is actually the same height. The portion of the manifold where the center brace of the hood is is about 11/16" lower and the rear (box) portion is a good inch lower. It sure looks a lot lower than that and clearance to the hydro boost is much better as well.

I'm using an Explorer throttle body turned sideways (throttle linkage down) with what I believe is a Crown Vic IAB (super short) nothing is above the flange on the intake manifold.

From my guesstimate you could add a WH integrated 1" body lift, use the tubular GT-40 manifold and add a 1/4-3/8" in body washers to the body mounts and be good. I have a Windsor waiting for a stroker kit that I will be installing some day. I refuse to cut my hood OR run a 2" body lift.

Good stuff right there ^^^^ Thanks needabronco!

i have seen a thread where someone cut out the raised portion of the stock hood a few inches and welded it back in, actually looked pretty good.

also this is an option as well.. http://bit.ly/1ThEWBP

I'm thinking more like this

I cut the hood.....GT40 lower and Explorer upper.

Any pics ?

Couple......

Is anyone familiar with height of 351 lightening upper intake ?

Wondering if it would be shorter than Explorer upper.

Tubular upper = Lighting upper.

Tubular upper = Lighting upper.

Tim

So they are the same as the tubular uppers from a mustang cobra ?

 

[mattt]

I don't think the Cobra came with the tubular upper, did it?

I haven't had a chance to measure my upper yet, but with what needabronco posted, the measurement on mine should follow suit. Here is the Lightning tubular upper. I started with a complete Lightning engine.

The one in the pictures came off a lightning (and yes they are the same as far as I know). Obviously your intake will be taller being on a Windsor. The one on the right is a 5.0 left 5.8. There's 3/8" difference.

I have a 1" BL from wild horses 351 lightning lower,stock mounts explorer upper same harness it all fits under a stock hood with some creativeness pm me and I'll give you some details.

Clue us all in...........please explain the creativeness.

My GT40 lower and Explorer upper hit the hood in a couple places before I installed the T-body which really hit the hood.

I see that you clocked the throttle body so that the throttle position sensor faces forward and that you ground down the boss for the front bolt on the upper intake.

Tell me more.......

 

[mjramacher]

Once you do that you have to find a way to hook up throttle linkage and some carefully placed play-doh on top of the intake and keep checking what is hitting and get it out of the way. I also cut down and re welded the coil bracket to get it as low a possible and some trimming of the under side of the center hood reinforcement.

Well here is what worked out on mine.......

WH 1" body lift with an additional thick fender washer which added another 1/8" to the body lift.

Turns out the motor mounts I was already using were the shortest version of the stock Bronco mounts. As Matt said, the actual height varies between manufacturers.

Explorer upper with 96 throttle body and throttle position sensor. This combination has the lowest height versus 97 and newer. The front part of the plastic cover for the TPS still touched so I raised the back of the hood up (it was a little low anyway).

Modified the coil pack mount to lower it. It only needed shortened by less than a 1/4" but I dropped it an inch just because.

Like mjramacher, I ground down the boss for the front bolt on the upper intake and trimmed off a little tiny piece of the hood brace where it was rubbing.

Thanks for all the input, it helped me keep my stock hood. WOHOO !

Great news and great job! I saw one at FFF like what you describing that seems to fit no problem really. I have the same 96 setup and was hoping to not have to cut the hood. Now with yet another example it seems just a matter of the details. Hank

No prob I'm glad it all worked out.
