Pick an RPM range you want to operate.If a cam is only slightly different,the engine will only behave slightly different.You said you want to go mid 11s,,,either cam will do that if the car is reasonable weight and hooks well. The 427 can rev to 7k and make good power.
close your eyes and pick a cam thats close to what has been mentioned.You want more? go 1 size up,you want less?,,,,
I have a comp cam in my engine,works great,makes good power,similar specs but in a small block, roller though
