You know I don't remember where I got this info.
I thought it was from the "New High Performance Hemi builder's Guide 2003 to Present" but after checking i could not find that info.
In that book the 6.1 cam is .571 lift int .551 lift ex 283 int and 286 ex duration.
valve overlap is 50.

Again in that book the the 6.1 cam 379AC is a 6.1 cam.
no info on the other.
