340 cam change

Mainly because for a street car, I've never been hot on really fast rates of lift. Those type of ramps are hard on the valve train.
Ditto. I didn't think the XE cams were really worth it for the street. Some report them to be noisy too. Maybe there is something between the repro '68 4 speed cam and the XE268 for a stockish 340 but I'm not losing sleep over it.
