Were I live Gulfcoast MS, there are no good buick v6 shops around here that I know of. So I have to resort to the local speed/machine shops. I would like to get a hydraulic roller camshaft installed in my 87 109 which I have recently taken out of the car. Can anyone tell me the labor cost that this should go for, and what is a good source of information that I can point the local guy to for install tips and must do's. Thanks
