88 sport rebuild , need advice

Reply #30 – July 07, 2013, 09:37:55 AM

with a 5 day windown, i am not sure we can achieve the air/fuel managment aspect properly based on all the info i am getting,,, this is disappointing.
I am electrical and computer savvy, engine building is easy if you do it right,, the knowledge of what works is way opinionated and it adds risk to the build knowing i need to make sure mason makes it back to work on time.

I'll give this another go and post a different thread that reaches out to stroker guys and what combo works for them.

Is the 97 explorer internal or externally balanced and what will i need by way of parts to address this?
I believe the explorer is internal ballance, will i need that flywheel that came with the truck?

after a few days off and on of gathering insight on this, i have concluded the time contraints we are under doesnt make a 331 roll out of our garage on time, with the sone in another state and having limited time to do this work, we are not going to stroke.,, i just need to call mason and let him know im out on the idea.

we will shoot for Mass air though as advised, and do a 306,,,
i posted a wtb topic on this and really need to score compatible parts for this,, making my MKVII HO EEC useless.
if we cant get the mass air stuff together in the next 3 weeks, mass air is out and the HO MKVII is in,

thanks everyone,, will update as i can,, i really hope someone out there has this mass air stuff, looks fairly simple to do up if Erics write up is correct. ,,coolcats.net that is.

Hey jcassity, it is simple to make up and install your own harness for converting the vehicle to mass. All you need is the connector some wire, a computer, meter and induction tubing, wiring schematic along with a little time. I will have to also say that the 347 issues were fixed years ago and thats what have been running in my bird for years at the track shifting it at 7000 rpm. I will have to look but I might still have my hand written diagrahm laying in my tool box.

the balance depends on motor/stroker kit.

82 and earlier are 28oz. 82 up are 50oz. just buy a stock replacement if you plan on doing a new stroker kit later. if your using an aod, parts should.be identical to stock.

Didn't think about that until you said somehting. Engine balance is crucial, mine is balanced at 28oz.

yeah,, that was my last question...
did i read this right,,,
can i use my son's existing flywheel or the explorer flywheel on this 306 build?

again,, the stroker is out,, we dont have the time for it.

..
.
and,,, can i graft the explorer fuel rail into the tbird fuel line easily,, I believe my 19lb injectors i have are all fine but 1 is a tiny bit damaged,,,,

The balance is a simple thing and needs to be dun anyway. What is the BIG DEAL!! There is all kinds of dampers and wheels to satisfy this. As a computer savvy guy Jay can install a stand alone and TUNE HIS HART OUT. The stock stuff sucks any way and a stand alone in my view simplifies the whole job in a nutshell. Running a small ford you need all the HP you can get because of the limited HP they produce. If building an engine of this type i agree stay stock with an overbore to clean things up and carry on. Either way you are limited but i would build a 347 if i was doing it. But to simplify the issue stay with a stock .030 over 306 and call it a day. just me THANKS.

im asking if there is a need to be discussing the flywheel or not.
I dont remember if the explorer motor i bought (which has not been delivered yet) has a flywheel.
Can i use my tbrid flywheel on the new motor,,, meaning earlier i asked "is the explorer internally balanced or not?

As far as i know they are externally balanced. Not only that they have different flywheel diameters and gear counts. If memory serves me 157 and 164 comes to mind. And if you mix them up the starter wont engauge. A different bell housing is necessary. I ran in to this many years ago so it is a little fuzzy to me. But as far as i know the 302 is externally balanced.

68-80 the 302 used the 28 oz imbalance
81 and later uses the 50 oz imbalance

WHAT!
why a different bell housing?
if thats the case,, im screwed,, say it isnt so tom!

i need this engine because it had a lot of goodies to donate to another future build for chance my youngest boy.

this block is suppose to be the block that goes back into my oldest sons tbird.
if your right,, im at a loss for words.

Jay,

I just did a quick Google search and even checked parts store websites and it looks like the balancer is a 50 oz. Jumped on the Corral and the guys there that have swapped over simply reused their balancer and flex or flywheel so that would definitely lead me to believe that they are 50 oz imbalance which makes sense. So to answer your question the Explorer motors are externally balanced at 50 oz just like all the other 302W from about '82 and up.

Someone on here or one of the Mustang sites will have a single 19 lb/hr injector for cheap so I would look at that route. You can score a lot of parts you need here:

http://www.car-part.com

I got my MAF and fuel rails for dirt cheap. You may even be able to find an A9L on there but I usually have better luck on the Mustang forums. One place that has the Mass Air conversion kit is Pro-M and its everything you need including the pins already installed on the wires. For $50 I think I would just buy this and be done with it then all you need is the MAF and EEC:

http://www.promracing.com/parts-accessories/wiring-adapters/mass-air-conversion-harness.html

The guys are correct that you can get more out of the motor with a stand alone but if you are wanting to just fire the car up and drive it then get an Mass Air EEC and the whole thing will be plug and play. I would not waste a dime on a stand alone on a 302 or 306 motor with the cam and heads you are going to run. If you go the stroker route later and up the anti with some heads and a good cam then it might be worth the stand alone.

Jay i think all late model T5 bells were 157 TEETH. But i remember some older units had different bell housings and gear teeth count. If memory serves me the EXPLORER has a 157 tooth count. I ran in to this a while back and it threw me for a LOOP. DCE corrected it for me and if i am correct all the later units that were sticks carry the same wheel and bell. I am not sure about the auto trannys . But i think they are 157 as well. Make sure you mock up everything before calling it a day. You dont want to install the wrong wheel and or bell setup. I know for sure the older small fords has a couple of different wheels and bell housings. Make sure you check it out thoroughly. My gut feelings is the late model auto uses a 50OZ wheel and a standard 157 tooth count.

Stacks corrected me on the 164 tooth count Sorry!!

Darren as you point out all the late models are 50 OZ if memory serves me. I respect your comment on the 9 ECM but a stand alone system is worth every penny. Even on a stock motor tuning is simple and straight forward. All the built in GLITCHES of the early ECM design is gone. I do agree that it is a cheap way to do it. But dealing with Ford OBD 1 systems is a real c. Granted you make a great point dollar wise but to add some SIZZLE to his project a stand alone will be a PLUS. Thanks

PRO/RACE #64270, PRO/SPORT #34270 and PRO/STREET #24270 - These dampers are designed for ‘81 and later 5.0 engines requiring a 50 in. oz. damper counterweight. Note that the stock damper is 6.38” in diameter while our dampers are 6.61” in diameter. As a result, there are some instances where the lower water pump bolt contacts the damper and some instances where the damper may contact the pump housing and/or timing chain cover. This is usually found on ’95 covers. Spot facing the bolt pad on the water pump and some minor grinding will alleviate the interference. This damper includes a sleeve and pulley spacers. See notes above ref: #64269, #34269 and #24269 for specifics.

Good luck JAY and check out every aspect of this project. These external balanced engines are a pain in the A$$. But 50 OZ is the ticket from what i can remember. Good luck and check it out carefully . Know the years of the engines and the type of balance you need. Cheers!!
