Im looking at a cam for my sbe 5.3 with 243 heads untouched on it now, with a super vic an fast 4150. nitrous motor in light s10 with a glide.....
specs are 235/255 .639/.632 112+4

i know a custom speced would be best but this motor isnt staying long so im just trying to change out the tsp220 in it now out for something little better.

 

That seems like an obnoxious amount of exhaust bias, even for a nitrous cam. But then again, I am no expert, and NO2 really isn't my thing. How big of a shot are you throwing at this thing?
