OK, I have already upgraded my fuel pump and exhaust system and upper intake .
I have a set 19LB injectors , a speed density HO ECM , a factory HO cam and a new timing chain .
I also have a timing gasket set and intake manifold gasket set .
I have 3 questions
1. Do I "NEED" anything else?
(I know E7 heads are in the list but I'm not swapping heads, if I were going to go through that much effort I would just swap the entire engine )
2. Has anyone done the conversion and kept the E6 heads?
3. If yes to number 2 did you have decent results ?
Back in 86 I had a brand new Mustang 5.0 LX coupe and I seem to remember it having enough pep to keep me happy for a while .
I'm assuming what I am doing now will give me similar grins :D
The E-6 heads are by no means "great", but, I did the conversion as you are years ago and even with those heads (which I later swapped to porter E-7's) the car was a blast to drive and you could feel the power difference in the seat of the pants. Compared to the SO 5.0, it will make you happy, and you'll enjoy it until you make more mods.
Oh, as far as parts, you have what you need ( You need all of your gaskets, etc). It is a good time to swap on new water pump as well.
Thanks Vinnie . I thought I had everything ,just wanted to make sure
Good idea on the water pump :D
It will be happening in the next week .
Pics and updates.
the HO I put in my 79 cougar is awesome, makes the car move like never before. I can only imagine what it would feel like in the lighter fox thunderbird.
What about exhaust? ;)
'Course, with E6 heads, exhaust really won't matter as much.
I already swapped to factory mustang shortys and a cat-less H pipe
Heck, at this point, should you DO decide to swap heads, I wouldn't even piddle with E7's....GT40's or some such...:rollin:
I always keep my eyes open ;)
All this engine talk is making me drool! I don't by any means need a street racer but I want my car to eventually be a good running street cruiser...
Ok another question
I opened the box for my timing set and it is not a double roller chain .
It is just a standard run of the mill timing set ,
Do i need to go back to the parts store ?
No, but I would. I got a double roller for my s.o.
Thanks , I will . What was stock on the SO?
What you have was stock on the SO engines.The H.O engines had a double roller.That's all I will use. Costs a few extra dollars,but worth it.
I just checked Oreilly's site it will be like 8 bucks more for the double roller ...I will be doing an exchange ;)
Now...wasn't that easy ?
LOL.. quick and painless , just how I like it
Are the SO 5.0's roller cams? If not, then the HO cam won't work too well in your engine. I just haven't messed much with the SO's.
If interested, I have two sets of E7's. One is in the process of being ported. The other pair are stock. I'll sell them really cheap!
Good luck!
86 and up SO are roller cammed so I'm good there :D
and thanks for the offer on the heads but I'm not switching on this engine , not to mention shipping would be brutal
Don't you need a Computer for the swap from non HO to HO.
I have an 88 XR7 Cougar and I am planning to do the swap, I already had new pistons (dished) installed in my motor during the prior rebuild.
I am purchasing an entire Mark VII "89" with H.O. Engine and from what I have been reading I can pull the Cam, heads, intake, and Computer from this Mark VII and put them into my 88 Cougar NON HO engine, change the firing order, Install Headers, and drive away.
Is this true? And if so what headers do I use, do the HO Heads have different Exhaust Ports than the Non HO Heads, or can I just throw in the headers that are recommended for my 88 Cougar?
Any help would be appreciated
All of that is correct.Plug and play.Yes,you also need the Speed Density H.O computer.It too is plug and play. You can use the H.O factory Mustang/Mark VII headers,but,you'll have to alter the rest of the exhaust to duals (well,you need to anyway),and the stock pipes will not bolt right up to the headers,also,the O2 sensors don't screw into the headers like they do in the stock Cougar exhaust manifolds.Get the Mark VII H-pipe as well.
Might be better off swapping the motor, and keeping your rebuilt one for down the road if you plan more mods/power.
Rocketman, you've got it pretty well taken care of, but as Vinnie mentioned, grab an H pipe from either the Mark 7, or from any '87-'93 V8 stang. If your standard 5.0 was rebuilt recently, may as well swap the HO parts onto it, unless you KNOW the jy block is fit for reuse.
The stock stang/mark 7 headers will work just fine for you...I have those on mine now, but am upgrading to some equal length shorties soon.
Got pics of your car? ;)
Well I'm late getting here , looks like they all answered your questions.
Remember that you need an HO fuel pump too.
If you have a complete Mark VII you should have everything you need
Absolutely, good lookin' out Wolverine..I mean hypostang :D:rollin:
I had the stock SO5.0 in mine, then it failed, so I swapped in a Walbro 255 pounder from a nice guy on The Corral, and it runs stronger and better, idles better and doesn't seem to have a "falling off" at higher RPM.
Yes,a new fuel pump is in order,but,your stocker will work until you can get a replacement.
Daryl, I have a set of E7's lying around. Let me see what kinda rates I can get on shipping. I can usually get good prices through work. If the cost is decent let me know if ya want em. I dont want anything for em, just want em outta my way.
Justin
Well, I "MIGHT"have an HO conversion engine :hick:
I started on it last night , worked from about 9 till midnight , then again tonight from around 8 to 10 Got it all back together .
I put my battery in and it was stone dead :mad:
Its on the charger right now
It did crank over about three times real slow and farted through the intake, and then the exhaust .
wen the battery gets some juice I'll go spin it over with my remote stater and a hand on the dizzy
.. Oh btw more good news I took pics during the whole process and none of them saved to my SD card:punchballs:
An early pre-start congrats to you.You'll love it. I have always loved the H.O in a T-Bird,and watching the Stang guys get really confused when you lay down a couple of real pretty black stripes.Stangs are the car of choice around here.
Thanks Vinnie , I'll let ya know how it runs when I get it all set .
I just hope I didn't screw anything up . This is actually my first venture into a roller motor, but it all seemed pretty straight forward .
It is straight forward.I remember my first one.Tom (turbocoupe50) was my tech center.At that time,I couldn't have done it without him.I was NEW at all of it.A lot has changed since then.He answered questions that probably seemed stupid,but at the time,I was basically starting from scratch. This forum has been more than I could ever ask and I doubt any other forum would be as happy to answer those "silly" questions about everything. Now,when it comes to big mods,Kitz is my main source of peer pressure.Without him,I wouldn't have installed Mass Air,the E303 in the other engine,and more.Basically a drill Sgt. over the net.LOL. Daminc for primary parts support through "ONYFTA" (Oklahoma New York Free Trade Agreement), and others that I have dealt with over the years,projects,troubles,and progress.Sorry for the lengthy pledge of thanks I had to pass out,but it's because of the people here that the Sport is what it is now. Always gotta remember what it took and those who helped to get to where you are.
I have been wrenching for as long as I can remember , but I only got my first computer in 2005.
I gotta say this forum is right up there with my favorites .
I was on another forum late last night and I just shake my head at the level of arrogance and condescension from some people .
On that particular forum if someone asks a "stupid " question the name calling and insults are unbelievable, and apparently nobody on any other forum knows anything about building engines :hick:
Whoo hoo !!
It runs well.
I have to re-stab the dizzy, I appear to be a tooth off, cant get my 10 degrees without hitting the thermostat housing .
More updates tomorrow :D
Got it timed, warmed up, no CEL ,,,, no license so I cant test drive yet ..
It sounds healthier for sure :D
Nice work.Now while you're waiting on the license,clean everything up real nice.
Carry on.
Rock on Daryl, Rock on:roxor:
Now I could "accurately" list it on Craigslist lol :hick:
1988 Thunderbird LX , Black, ....{"5.0 HO"}..... engine :burnout:
Thanks Justin , I couldn't have done it without the good deal you gave me on the parts :D
Just make sure the dizzy is right on because the EEC uses the little vanes on the distributor to time injector firing.;)
