Anyone have any experience with changing cams in crate?

Is this the cam spec on the crate 380 may I ask? thats not what ive been told....curious.......well as far as performance...it honestly doesnt pull as well as i though a fairly light car with 400hp should. Idle is fine...drivability is good.....my buddy has a shivvy lightly modded 350..nothing fancy, auto car with a gearsvendor set up and that thing runs and revs like crazy...and again it aint nothing big dollar and its not a stroker....plus its a heavy car Im sure., (camaro).....thats what i compared the duster too when i first brought it home......cant be having no shivvy running better than my mope..lol......I know I know...havent runem...or taking it to the track.....I know his then ran low 13's, he might of touched the 12's not sure....but he since has got another motor in the car that in the low 12's.
