TRW cam?

A friend has found a good looking 350 with edelbrock intake in an old GM van. He has it apart and it looks promising for his old Camaro. The block casting is 3970010 and he was pleasantly surprised to find it is a 4 bolt main so maybe it wasn't the original engine in the van. The cam looks good and the only numbers we see are TM274 on the end. The only thing that comes close on my search is the TRW cam. Can someone confirm that it is TRW and if so would you have the dope on the cam itself? Is it a performance cam or should he be looking for something more radical to get some performance but still use it on the street.

If it's in a van I would imagine it isn't a very large cam.

The engine number V0202TDY. The T should indicate truck but I can't find suffix code DY anywhere. Would like to find out more for him, thx
