I just bought my first car. It's an 85 Oldsmobile 442 with a '71 model 455. I am interested in sqeezing some more horsepower out of it, but I have a problem. All the big dealers (i.e. Jegs) have all the parts for big-block Chevys. Are there any parts that will fit my 455? And if not, where can I get a good catalog for my G-body?

 

no chevy parts but try competion cam's crain cams ,holly eldebrock and offenhouser to name a few .good luck .
