Hi everyone. I'm new today because I need some help. I have a 83 K10 w/ 350. I havemade some upgrades to the motor: Edelbrock intake and Carb (600), headers, and an MSD 6AL. My truck seems to not want to start on a normal basis, and when it does, it will stall after revving the engine and goosing it. Any suggestions? ***Update*** After letting the truck sit for a couple hours, I went out to start it and it fired right up. I let it sit at idle without revving it this time to see how long it would run. It ran for about five minutes, or about as long for me to go inside and check this website for any replies, and then it just quit.
