so i picked up another 95 gmt400, and it has the 5.7l motor in it, after about 2 to 3 hours of driving it would start to knock, i parked it and let it sit, then i drove it again for about 6 hours let it sit idle and all that fun stuff no knock this time, could it be a bearing on its way out, oh plus it has a bit of a missfire
