Well, skipping the engineering issues for a moment, the current cam is designed for less boost than the new cam. As boost increases, cam duration decreases, and in my case, exhaust lift increases due to the NOS. Hell, the 8-second turbo Mustangs run ~220 duration. In another post I stated that these relationships are parabolic in nature.

Jay Allen (mustang tuner) told me this years ago and i couldnt believe it.

Lots of renegade cars into the 8's with very small camshafts. It's all about knowing wtf you're doing.

well my 388 all bore is getting a:
Comp grind 244/252, 0.597"/0.597", 110LSA hydrolic roller cam.
I don't have numbers yet (still putting it together) but I'm sure I could have done larger (if I wanted/needed to). This is my daily driver (M6) so I wanted to stay <0.600" lift for valve spring life.

I wanted to make sure I could get all the exhaust out of the cylinders, though now that the heads are back (made some improvements) and flowing 240CFM (exhaust) it looks like it wasn't really needed

Personally, I have difficulty using that much duration in a hydraulic setup. Unless the ramp is pathetic(which I don't presume it to be), it is not going to last particularly long. You're into the solid roller range.
