Best 318/x-head /hyd cam combo

So I planned on building this 318 in my Dart;I have the x-heads getting new stock valves,double springs,etc. I bought a new MOPAR 508" cam from Hendricks but upon opening the box found the brand new cam broken in 2-right about dead center!!!!!! This got me thinking that it may be a bad omen. For a street /strip would I be better off with my COMP .477/.480???? I have 4;30 gears , Hooker street headers with 2 1/2" dual exhaust.
It's a 2 door, no a/c,no carpet, manual brake car, 650 Holley double pumper, manual valve body 904.
The idea is to go mid 13s don't care about the MPH or the MPG
I haven't had it to the track with the present 360 heads because the guides are worn so bad that with the oil smoke coming out of it ,it looks like it 's Ford powered(Fords and oil-they either leak it or burn it) .
