Has anyone done this to a truck similar to mine?
I am interested in:
-How was the perormence gain: Better over-all, not so great?, if better, more in low end or high end improvement?
-How hard is the install? Is it likely on an engine 6 years old with 63,000 mi that the intake bolts will seize or break when I try to remove them?
- Is there a website somewhere that shows the torque specs on things like the intake manifold bolts, water pump bolts, etc?
- What the stock size (mm) of my throttlebody?... even the Ford dealer wouldn't tell me!?
- Should I just do the intake manifold and use the stock throttle body, or visa versa, or both, or none of the above? I'm running out of bolt on performance mods!

Thanks guys!

Well, I can only help with a few questions so someone else will have to handle the rest. Your 5.8 comes with a dual bore 50mm throttle body. Are you thinking about going to a 56mm dual bore such as BBK sells? Sometimes this can be a catch 22 because if you don't have enough air velocity (caused by going to big) your truck engine wont perform as good as it would with a smaller T body. But, if your engine requires more flow than the stock 50mm can handle, it would be beneficious to upgrade. But for the small gains I personally wouldn't unless you absolutely need to.

Also, about the intakes...Im not so sure you want to be adding performance intakes. Since we are dealing with a heavier vehicle low muscle is generally better unless your running for 1/4 mile times. Almost all performance intakes take away bottom end in exchange for upper. In fact, some even bog your engine down untill you hit 4k plus. This isn't good. So unless you are building a very high horse power engine I would probably save the money and stick with the stock intake. They make good low end torque. Maybe find a cheap set of GT-40 heads for a moderate performance boost. New in summit they are 500 bucks. Or upgrade to the Rousch 200 heads for around 800, TQ has raved up and down this board about them. Only bad thing about this mod is you basically have to strip down to the shortblock . Those T-bodies alone are around 300.

 

Thx for advice, appreciate it very much! Yes, I am looking at the BBK 56mm. The tech guy at edelbrock swears that the intake (Performer series, NOT Performer RPM series) improves low-midrange, not high end - they claim 34lbs more torque, mostly 3,000- 4,000 RPM range which is good by me and should help towing, too. I agree w/you, I don't need bogging at low end or any sacrifice at low end.

The question is do I believe Edelbrock's advertising claims below? This is kinda expensive. I'll do it if I could be sure it will work.

Here is their adverstising says:

Ford Intake Manifolds for 5.8L EFI V8

Performer Truck 5.8 (Idle-5500 RPM)

Performer 5.8 aluminum manifold #3881 is designed for 1988-96 Ford trucks and vans with fuel injected 5.8L V8 engines. The modular design incorporates the latest air flow technology and design for maximum torque gains in the mid-range where trucks need it most. This manifold made 34 ft/lbs. more torque than stock on our test engine. Other features include: broad power range from idle to 5500 rpm; removable plenum cover that allows access to runners; base manifold is CNC port matched to upper manifold for maximum power; and accepts all stock hardware. The upper and plenum cover are powder-coated light titanium gray. The base is as-cast and not powder-coated. Combining the Performer Truck 5.8 manifold with other Edelbrock Power Package parts gives you even more power across the entire rpm range. Use with stock Twin Throttle Body, or for even more power use Edelbrock twin throttle body #3837 or #3838 (#3838 requires port matching to manifold). Stock replacement and street legal for 1988-96 5.8L engines in all 50 states. See Power Package Graph.

Performer 5.8 (EGR) #3881
Installation Notes: Recommended intake gasket: Fel-Pro #1250.

Edelbrock/BBK Twin Throttle Bodies

Designed for 1986-96 Ford trucks with fuel injected 5.0/5.8L V8s. The 56mm is the optimum choice for the Edelbrock 5.8L EFI intake #3881 and Power Package. Our 61mm throttle body is intended for more radical engine combinations and requires port matching to fit most manifolds. Gaskets included. Street legal in all 50 states (E.O. #D-215-18).

i am bought the truck intake from jegs earlier last week, and i will be getting in the mail tomorrow hopefully and install it next week, i will come back to you w/ results

i also have a 96 351 Bronco

EDIT: did not realize how old this post was, i googled and found it

hey, 1rocket. I am also looking to do the same with my 96 5.8. I've been a bit leery on the results I may get after install, but I believe we are after the same results (a little quicker without sacrificing too much low end power). I also wanted to add that I am looking at the same exact set up from a local auto parts store. So my question is, where did you come across the info on the set up and how much are they asking for it?
I found it at checker auto for $721 for performer intake and I don't quite remember how much the 56mm was.
You posted that you also added the hypertech III. I was wondering how the improvements are to the 5.8L. When I went to chek around for the hypertech III the salesman told me that it would only change my shiftpoints. Is this true?

 

I don't think you're going to get a reply from 1rocket, he hasn't been on since November of 2002! Maybe someone a little more current will read your post who is familiar with this installation. Let's see how Lucky 13 does with his.

 

For the price of the manifold and the 56mm throttle body, you could buy a nice set of aftermarket heads and get alot more performance gain for your denero.

 

The Edlebrock truck intake works very well on my truck and made noticable power gains, now the 56 mm throttle body actually hurt performance and I am now running the stock one again. The factory t-body is 50 mm but it does look alot smaller compared to the BBK 56 mm unit. Skip the throttle body unless you have good heads and a decent cam.

Oh yeah the install was fairly easy and I didn't encounter to many problems.

 

Well the truck intake from edelbrock exploits low end tourqe so its a worthy investment. T-body not sure but I wouldnt get one until I got some flowing heads...A large T-body on a stock motor can make it fell alittle soft on take off... But 56 isnt that bad. This post Is very old but hey maybe someone will see it and use it for the info. I would get the intake and use the stock T-body and just try to port match as best you can with this until a head upgrade...then throw on 56mm t-body.IMO

 

i was in the performance and general engine forum and i came across something i have never thought of before. it was a kenne bell supercharger for my 5.8L. have any of you fellas ever heard of anyone placing one on the 351 5.8L?? and if so, what were the results? i went to the website (kenne bell) and read the FAQ's for about an hour just to get the info straight on this product and it all sounds pretty solid but, after all why wouldn't it sound good on their own website?!?!? thanks for all the advice fellas, that's why i love this website!!!!!!!!!!!!!
