Where did you get that cam?[/QUOTE]
I bought it about 10 years ago (my project is taking a loooong time...), so I'm going off of memory, but my guess is that it was through Summit or Jeg's. My understanding (again based on memory) is that it has the same specs as the stock 68 340, but maybe that is not completely correct. I need to check to see if I still have the part number and/or specs for what I bought to confirm either way.

There is a section in this which mentions the 68 340 hi po cam:
"Camshaft is the next best upgrade you can do for the 318.
They really like the 340 hipo cam, which is still very mild, but is just enough to wake a 318 up. It has a lift in the .440 range, so any aftermarket camshaft between .430 and .455 work really well and mileage will not suffer, won't have to be high compression and doesn't require any high torque converter. Any more than that and you will kill the bottom end and the 318 will run like junk. This is an excellent cam for the 318.
318s get a little radical with a cam larger than .450 lift on 270+ duration, 360s get radical when you get up to .485 and 290+ duration, so a .450 lift and 270 degree duration in a 360 screams, idles pretty smooth and will get a little better mileage without any sacrifices. "
