Ok, about 30 years ago i bought a 57, 371 olds motor from a guy that said he had it in a 40 ford pickup. Said it was way to fast and decided to install a tamer motor for the wife to drive. "at least that's what he told me". Since life got in the way, i just decided to pull it apart last week and take a look. Been bored about 1/8" or 3/16's over and has some neat boxed rods, and bigger valves and had a J-2 tri power with bigger end carbs. Anyway i pulled the cam out and all i could find was it has MTC stamped in it, which i assume is a melling. It has R-8 stamped on the front and H-209 and ROC-1 stamped on the back. I try to search but could not find anything with those numbers. Seems melling has different markings now days. For all i know, it could be a stock J-2 cam. If anyone has any info, i would appreciate it. Next, is to figure out who's rods are in there. At first i though of Don's speed shop in Gardena, but not sure. Thanks.
