I have a Crane HT-288-2-NC in my 396. this cam was installed 23 years ago when it was rebuilt. I have the info card but there does not show a listing for duration? I am hoping to rebuild and want to upgrade perf if possible without totally losing street manners. 
I have listed what the card says in hopes of an interpretation from someone.
Lift@cam 287 / 298 Ratio 1.7
Lift @ valve 488 / 508
valve timing
open 33 / 82
close 75 / 36 at .004
.050 lift timing
open 0 / 49
close 34 / (-5)
Right now I have The stock high rise / holley 650dp / headers / turbo 350 w/shift kit / posi 3.55 / mallory unilite
I would appreciate any input or suggestions.I am open to anything but really need to get it right the first time( kids , wife and $ dictate one chance for the next 23 years!)
