Trying to figure out what is going on here... besides what looks like some oil in a new motor, well 10K on it. Has never run right since build and a chip from... well you know that ones that never run right.
Since the truck came with no knock sensor and the chip is in question he is mailing it to me. I'm really worried this is another 454SS timing table in a tow rig hauling 12k
