Hi all, I'm new to the site. I have a 1995 Riviera with 156,000 miles on it. The car developed a rod knock, and a main squeek within the last 500 miles. I am pulling the motor this week. My question is, is there a good place that sells aftermarket parts for these motors (series 1 L67). I know its the only year they put this motor in the riv's. 1996 it changed to the series II. I've been told that the heads and intake are different from gm. Any help would be great.

Thanks,
Mike
