I have read a couple examples of people running the lt4 hotcam even on stock exhaust with no problems and that cam is listed as 279/287
Interesting thread.......
I am currently modifying my Vortec heads after lessons learned re: cams/lift/coil bind/rocker studs/etc........
See link below :
If I had to do it over again I think I would have gone the E170 Head route.......or something equivalent, and upgraded to a stroker.
I went w/ the CompCams XM270HR cam and had coil bind issues.
Question for the experts: When we speak of max duration, is it the Intake or Exhaust duration we are referring to?

That's nice. I like the 110º cam mod. That will help the reversion a lot. Good call.
