Hey guys I just purchased an 1988 f150 with a 5.0L, and after I verifiy that all the saftey gear is in tip top shape I plan on adding some performance parts to it. What have you guys done and in what order has it been done. Also, this is to be my 2010 bracket racer/daily driver while I finish the build on my 66 F100, so I cant really hate driving it to work.

 

what transmission do you have? and what axle gear ratio do you have?

 

It has an AOD not sure what gears yet as I am to lazy to crawl under it and look at the tag. But I probably will do that tuesday.

 

just give us the axle code on your door jam. you cant do anything serious to the engine with an aod, they couldnt handle much more than a stock engine with the stock 2 piece lockup input shaft.

you could insulate your stock airbox and hoses with foil faced insulation, cai's dont do much if anything.
you could advance your timing a few degrees, thats basically all chips do, but chips are 240 bucks more than advancing it yourself.
upgrading exhaust will help a little bit. a single high flow cat and a si/so(or dual out if you prefer) straight through design muffler will help a little bit.

theres quite a few threads on this subject if you use the search feature.

 

I'd start w/ this:http://www.youtube.com/watch?v=D11ZV...eature=related Ignition upgrade & timing bump: http://fullsizebronco.com/forum/show...ht=timing+bump & a K&N drop in filter . CAI's are to much air for a MAP engine (they'll lean out). Try to get 16BTDC if the engine is healthy enough (at least 13.5BTDC). Then: http://performanceunlimited.com/docu...degapping.html

 

thanks for all the help guys. Keep all the good info coming! I have one more question to add after doing a little researching. If the engine starts to lean out due to airflow enhancements, will adding fuel pressure help? Also can I change injector size without too many problems? Oh and one more... Will fuel rails and pressure regulators interchange between mustans and the pickups?


PS will the seafoam clean out egr passeges?

 

If the engine starts to lean out due to airflow enhancements, will adding fuel pressure help? Thats' an interesting question. I would say no, for the reason that it's not so much a question of whether there is not enough fuel to achieve the proper air to fuel ratio of 14.68:1 , but the ability of the engine to monitor and adapt to the air increase. A MAP engine is restricted to reporting changes in air density, not actual flow which is why people do MAF conversions.http://www.dunne-rite.com/ (also w/ MAF you get sequentially, fired injection) Also can I change injector size without too many problems?Not that big a deal. Oh and one more... Will fuel rails and pressure regulators interchange between mustans and the pickups?I would think it would be specific to the engines demands rather than what the engine is in.


PS will the seafoam clean out EGR passages?Somewhat, but nothing beats removal and a good douching. It's easier to check function & diaphragm integrity also. Pay attention to the manifolds EGR pathways as they can become partially restricted themselves.

 

Thanks for the link. I might do that. I prolly will just clean the EGR passages and stuff when I remove the upper plenum to do valve cover gaskets.

 

OK I just got the info off my door. WB = `133, Type GVW = F154, Body = TG4, Trans = T axle = 19 (might be 9 but I cant read my writing) Tape = 3, Spring = C V, and the VIN is 1FTDF154N4JK84629 Can anybody decode this?? And the Diff tag says 3.55:1 gears

 

I think you're missing a few digits there from your VIN number. Axle code 19 is a 3.55 non limited slip.

 

All 17 digits are there. I counted

 

The VIN is way different from most modern ones.

 

Will Be paying of the truck Monday then all the work begins. Its going to be a mad thrash to get it ready before the first of April!

 

Seafoam's more for removal of combustion chamber deposits, which it does well.

 

Wound up pulling the upper intake manifold to replace the valve cover so I just threw the thing in the parts washer at work. The throttle body is very gummed up its taking a coupe days to clean with Throttle body cleaner. But its comming...
Starting to panic a little bit though race season is a month away and I still have a lot of work left to do. Any body wanna help
