Which Cam - 240/244 or 239/247
Let me make this as painless as possible. This question has no legitimate answer. Since our engines are mass produced there has been proven differences up to 20 hp difference between engine in the same cars made in the same year and month. But you'll have every one try and make a shot in the dark guess.

You may get some legit ponderings if you broke it all the way down to 2 cam only (w/valve train mods to support the cams) 19XX or 200X LS1's on the same engine dyno...........you might just want to ask about the characteristics of each engine based on each cam design.

The one that is well supported (modwise) will get on top. It is really splitting hair between the 2. One is XER/XE and the other is LSL, valve events are almost identical, 240 at 18* overlap and 239 at 19* overlap

I have the second cam but on a 111+4 and 243 exhaust lobe...times in sig 
but seriously both cams will be very close to one another...make sure to check PTVC with both...if it is more a street oriented car you might want to go with a slightly smaller cam in the 23x range...it will make plently of power trust me, my cam only times are with a 230/230 predator z speced cam
