Hello guys,
I have a motor with GM cam 3904359 in, and I'm trying to find out what the specs of it are. The parts book I have lists it as 350I/352E duration - but this seems unbelievable (or maybe I don't understand the notation properly). Another source says it's 278I/289E @ .006", 114 degree LSA which seems OK, but I don't know how reliable the source is.

Does anyone have a parts book they could look up the correct, and complete specs in?

Many Thanks
Matt
