My long term project...

[BUBBAS 666]

I'm in the slow process of doing some real beefing up of my engine.

Here's what I have planned and I need someone to tell me if there are any holes or flaws in my idea or parts matching up.

1. Ford Racing GT-40 Heads- Part# FMS-M-6049-X306 OR Trick Flow Specialties Heads - Part# TFS-51400004

2. Edelbrock Performer Truck Intake- Part# 3881

3. Comp Cams Magnum Hydraulic Roller- Part # 35-302-8

4. BBK 61mm Twin Throttle Body- Part# 3505

I'm also going to upgrade my exhaust system to better headers, I got the ones I have now because I like the way it sounds and it was cheap lol.

Can someone tell me if I've got anything going for me?

And does anyone have any opinions on the heads? Which ones are the best bet the Trick Flows or the GT-40s?

Can anyone tell my what hp gains I'm looking at?

I have a 96 which is MAF.

yo!

sorry for da delay,,,

some info can be found here; GT-40 (or stock) Heads Swap in an 88 F 150 5.0

Source: by josh88ford Sorry to route to another site, but he has a lot of relevant info there.

Ford racing claims 65 HP with their Alum. "Swirl" design GT 40's, so figure on about 20-25 RW HP gain

GT-40 heads vs. Ported E7TE Head Flow Tech by Peter T

I agree w/GT 40 heads, because they are readily avail. at a nice $ due to their use on many Explorers...

also read this by Ryan

Edelbrock Performer Truck Intake EB claims up to 37 HP at 5,500 RPM

BBK 61mm Twin Throttle Body- BBK claims "ADDS 8-12 HORSEPOWER"

Comp Cam - about 20 hp

the exhaust will help a >> lot!

GL!

Ok, thanks for the reply man!

That's just what I needed!

Hey, miesk5...

When I posted the cam option the other day, I didn't even think to look at the lift and duration.

It's .533 and I know that's WAY too much lift. I've found another one with a .512 lift and a 270/276 duration. Would this be ok? I'm running MAF and stock springs/everything.

Do you think I could run that cam right now without any other mods like springs, rockers, etc? I want to put it in before I get my completely assembled heads.

Your thoughts and recommendations are much appreciated.

Thanks!

yo B!

YW!

ok, now I wade into da alligator swamp...

GT 40 cams have just .282 of lift..for intake & same for exhaust

** cams run mostly .278...some as low as .237

"I didn't even think to look at the lift and duration." neither did I..that's what I get for rushing, sorry...

"...It's .533 and I know that's WAY too much lift. I've found another one with a .512 lift and a 270/276 duration. Would this be ok? I'm running MAF and stock springs/everything..."

ok, now the swamp.. I call it this because of all the factors going into an EFI/MAF equipped vehicle..mainly State/Fed Emission Laws and INSPECTIONS....here in NJ (where my Bronco is pulled aside every 2 years and inspected by people in Black Suits and ties) thesechanges could cause me probs in future. Due to ever changing State Emission/Inspection laws and made-up "rules"...latest made-up rule is automatic failure for a tranny leak...so, if I cjange my E4OD fluid and smoe stains the tranny pan... yeah, they failed me last MAY..

ok, read this EFI Performance Article by Ryan M

.. pretty good stuff and he knows Ford EFI very well

Next, is his info on How to pick a CAMSHAFT for EFI

"...

For a good fuel injection truck cam:

intake duration @ 0.50" should be kept at or under 210

Gross valve lift should be kept under 0.500

Lobe seperation should be at or above 114

 

[BUBBAS 666]

Ok, thanks Miesk.

I did read the "How to pick a cam for EFI" from FSB forums, and read the entire 12 page thread, but I left more confused than when I got in there... and I don't dare ask a question there because it seems FIREGUY (no offense if you happen to read this, it's just what I see) likes to feel superior and make other people feel stupid for not knowing something.

I have checked out those Cams and did notice that the thread said EFI CAMS, but was really referring to speed density and not MAF. My main question is, since I did pick a cam out from that list you provided, will they all work with MAF... or no...?

According to the article, a reprogram of the ECU should be done after adding a cam and intake. Did I get that right?

A dyno would be able to do that right?

I don't have my EGR hooked up because there was no connection for it to my header... what am I doing to the computer by this and can I just simply go into the computer and shut it off?

Sorry for the seemingly stupid questions... I'm just getting into the performance aspect of engines, been on the maintenance side since I started working with em'.

That's some ridiculous S*&t you have to go through for a simple inspection.

That's why I'm glad Ford sent me to state inspection school to get a license lol.

Thanks Miesk!

yw Bubbas,

In his website, Ryan writes; "...Large cams that cause a surging or pulsing of air at idle will confuse a Mass Air Flow EFI system, making idle quality suffer. If you still feel the need keep the lobe separation of the cam at or above 114 degrees. Be cautious with lift over 0.5�; any more might create an interference if the timing chain brakes..."

ok, we'll need to cross-ref the Ford part numbers to those shown in Ford Racing Catalog;

Some info for you from the Racing Cat;

"...Ford Racing Camshafts

The Ford Racing Camshaft Specification chart describes individual cams currently available from Ford Racing.

Refer to page 216 for performance characteristics and usage guidelines. See page 115 for valve springs.

- on page 126 Ford shows specs w/part numbers and Notes;

NOTES:

1 On EFI engines, performance camshafts work only with mass air induction

systems. Will not work with Explorer EEC-V EFI.

2 Also fits 1994-97 351W with factory roller cam when used with mass air EFI.

3 Stock 5.0L ** cam advertised specs are 266

More; if you plan to pull more out;

Malfunction Indicator Light (MIL) Eliminator, for a Mustang, but similar, make your own with Radio Shack parts, Scroll to page bottom

On the EGR.. you can also make or buy a block-off plate and then have the tuner do their thAng on the Chip or a another device..

Also consider Thermactor Smog Plugs by Ryan.. diy and save $.

what else? I'm trying to re-think da plan. Since you'll ensure all is done to local/fed laws on emission..etc..and you'll inspect it later...what else do you want it to do? strip racing on week-ends? etc.

and about this in your signature; "...Diablo Sport Extreme Programming Chip & Professional tune.." was this done recently?

If so, how did it work-out?

Back to da Best 5.0L/5.8L (302/351) Roller EFI cam:

89-95 Mustang 5.0L **

Ford Part numbers: E8ZE-6250-CA / F1ZE-6250-AA / F4ZE-6250-DA

* Advertised Duration: 276 / 266

* Duration at .050 in.: 214 / 210

Thanks again for taking the time to give an in-depth, informative response, Miesk.

I'll be going with the E303 cam. Now a couple more questions, will I need new valve springs, lifters, pushrods, rocker arms, or anything else to slide this right in to a stock block before I get my new heads? I ask because I want to get this before I get my new heads. Where would I get a higher stall torque converter, and would I need to upgrade anything else upon installation? Will it affect daily drive ability?

As for the EGR question... I went to my local dyno and asked them about a chip I want, DiabloSport Delta Chip. They said that when they burn the chip, they will permanently turn off my EGR and my O2's. So as long as they are turned off I'm happy. Not the CEL, I can turn that off myself... I want the sensors turned off and they'll do it. I'm not in a rush to make my compartment look nice, I just want to crank out some more power. The chip in my sig. is in the "I want to's" section of it. I don't currently have a chip. Maybe I need to refine my sig. Less "I want to's" and more "I have's."

I'll be studying the Ford fuel injection site, so hopefully I'll be more able to understand EFI performance better.

Thanks again Miesk. I really enjoy reading all of your responses, not only to this, but just about every other thread in here. You sure do know your stuff!

yo,

According to the Ford catalog and Roush cat; the M-6250-#E303 does not req. longer push rods, etc.

I always liked Art-Carr products; incl the of high stall speed torque converters

back here for a few before I have to roll...

Tried to send you a message yesterday about the plan and what products you choose re: HP/Torque peaks & curves.

One thing that could contradict the cam change, etc. would be exhaust header, flow, tubing, etc. sizing.

ok?

& the Diablo tuners. What else have they said that they can do?

Have to find info that will help you and ME understand what can be done to our 96's ODB II EEC V as compared to later years of Ford OBDII. Think the simple answer is not much as compared to a 2001 F Series or Lightning, mustang etc.

later..
