just rebuilt have problems need help asap!!

Just rebuilt car, its an 88 mustang 302 with mass air. F-Cam, Vortech a-trim blower, ported gt40 heads, ported cobra intake. Only thing done after rebuild was the cam change and ported/shaved heads n ported intake. Installed new 190 lph fuel pump and filter. Car starts when cold now but stalls out after about 15 minutes. Will not restart just turns over n over. Its possibility but not certain that the fuel may be being cut off. Anyone have any ideas?

How does your oil filter and pump look? Your using a carb correct?

Modifying newer vehichles(well cars with sensors and a computer controlling the engines/transmissions operation)Scare the hell out of me. when it comes to altering the simplest item like going with a 160 degree thermostat leaves me to wonder how is this going to affect the computers ability to maintain proper operation. Did you change the computer chip to compensate for these alterations?

Im sure that it can be done, you have mentioned the vortech blower and another non stock cam. Is the cam made to operate with a blower? Also by shaving the heads you will bump up the compression ratio. Using a supercharger requires less compression, as the supercharger builds the compression before the air-fuel charge enter the combustion chamber, this is one of the reasons you would want to have a supercharger in the first place. The blower is releaving part of the parasitic nature of the compression stroke.

Im sure that these aftermarket parts have instructions,guidelines, or recomendations, to matching these parts. Whether a vehicles motor is built to tow, drag race, or simply get you from point A to point B, The parts have to be matched to operate cooperatively. I wish I could offer first hand experience to help you in your delema, hopefully some one out there has gone through what you are experiencing here. Your project seems really cool and I would like to know how it turns out, Just dont give up, one of my first projects was when I was a teenager changing the intake and cam in my 81' F100. Even though I was very carefull, I made a very simple mistake, that resulted in me selling one really cool truck dirt cheap. I couldent get it started it would turn over and over but wouldent start. it drove me nuts, after I sold it I found out I had left the battery connected during the work and melted a fusable link. I sold a really cool truck over a stupid mistake that could have been fixed for $5.00 and ten minutes of my time!

Also I remember a previous post, we were discussing an overheating problem, and the computers Air fuel table was brought up by Psychopete any way during cold operation the computer uses a fixed table until it comes up to operating temp (160 deg.) then it uses info given by the various sensors particularly the O2. hope it helps.

Im no expert but have a good friend that has a built 306 including 175 shot of nos all the goodies over 25,000 in car and he didnt have to change the compter it just takes it around 30 seconds to read and compensate.I worked at a ford dealer for a bit(ase cert.) and to me it sounds like you need bigger lb injectors if you dont already have them but like i said im no pro at high performance i just worked on regular fords and a few lightnings.Hope this helps
