First car I ever drove was an Oldsmobile. Drove many since then, too bad they're gone. I posted some info about the J2R because this was the only place I found any info at all on the engine, which was helpful. I posted some pics there and will post more later.

 

A little more info needed. I'm more into the early 50 era Oldsmobile's, are we talking about a J2 setup on a 57-58 371 or a completely different car/year. I'm ignorant on the new stuff .... Tedd

 

Yes, it’s a 1957 J2R. I posted more info in the other thread about J2’s.
