I have an '89 lx w/ a 302, 40 over w/ trw forged pistons, eagle forged rods, ford racing crank, ford racing e303 cam, trick flow twisted wedge heads, trick flow upper & lower intake, bbk 65mm spacer w/ bbk 65mm throttle body and a cold air intake, it also haves a msd 6al box, msd blaster coil, msd distributor and a superchip, 24lbs injectors and 1 5/8 mac shorty headers, It runs terribly, cold start are hard it stalls and conks out. When it is running it pops out of the intake, and the power seems to come and go any suggestions would be greatly appreciated

Honestly how is the condition of the cats? My car has been running like how you described and it turns out my LTs either melted them or they are hopelessly clogged. That would be my first check. And you can run the home test and pull the codes using the self test on the EEC. You just ground out the self test plug and the CEL will flash giving you codes. If you can findthe codesor someone can post them, your car's computer should tell you all that troubles it.

what is your timing set at??? also how is the harmonic balancer....may have shifted a little on the rubber giving an inaccurate timing reading..I had this happen once[:@]

Check for vacuum leaks. Is the MAF filament dirty? Try spraing it with brake parts cleaner.
Sounds lean to me.
