I recently finished a rebuild of a 289 in my 67 vert. I originally let my father, a Mopar guy, set the valve lash , resulting in a cracked cylinder head and 4 burned valves.
I rebuilt the top end of the engine with powerheads, rollor tip Comp Cam rockers, a new hydraulic Comp Cams cam with new hydraulic lifters and a dual timing chain. He tried to put the double rolller chain on a stock cam before but it kept slipping off of the cam end and the pin would not set properly in the gear. He, instead replaced it with a regular timing chain. In my genius mode, I decided to try the double chain again. It fit when I had the timing chain cover off and completed the engine work.
About a month ago, I finished with the install and got the engine running. All of the sudden I heard some noise form the engine and the fuel stopped going to the carb. I replced the fuel pump but it still did not work. No fuel was making it to the carb. I replaced all fuel lines to the pump thinking there were kinks in the line or clogged lines. Still no dice. Finally, I replaced the mechanincal fuel pump with an electric fuel pump. The car started immediately. I had a little trouble setting the timing but finally got it to start running but it would die when it started. I readjusted the timing and got it to move. It was the smoothests I have ever felt the car run ever!
I took it on a short trip to have it die again. I started it in park and dropped it into drive with a loud pop. After that it would turn but not start. I puched it back into the garage. The next day, I took off the distributor cap and turned the crank to check maybe if the timing chain had come off or somthing and the distributor would not move.
I think the timing chain may have cropped out on me but am not sure.
Any suggestions where to go from here? I figure the car is done till the spring. I am having a 4V intake redoen and a 4V 4100 autolite rebuilt t0o put on it now so If I need to replace the chain, the work can be done.
Any help would be greatly appreciated!
