97 camaro LT1 w/ longtubes, cc306, stageII heads, 6 speed

4 weeks ago i began the install of ported lt1 heads and cc306 cam. we droped the motor to do the work. After the install the car was running perfect.. no missing and it was smooth. ok a couple of days later the car started knocking so again i pulled the motor and found that it was one bad baring.. so i replaced the crank, oil pump, and bearings. ok now the car is back together and it misses after the car warms up. first 5-10 minutes it is perfect after that it falls on its face. I replaced the plugs and wires and even switched to taylor over the tops. i am positive that it is not the plug wires. Also replaced the coil. I dont know what to change next. please help!

Thanks
Erik

 

I have the same problem with my car after it warms up...only i have changed the battery, computer, had computer programmed,changed spark plugs, coil, ignition module, radiator. But still it runs great for 10 minutes, then the engine dies.
