Thank you for your quick reply. I got busy and haven't had time to work on this truck. I tried to look at the photos by updating my account to allow third party hosting, but couldn't figure that out either. Also, I thought I should be able to correct the timing chain bad alignment by rotating the cam to the correct position and replacing the pulley??? The truck runs good at high rpm, backfires under compression going down hill, and idles erratically. There still is a problem with the vacuum lines not being hooked up correctly.
