My choices are both mti cams
1 being mti X1 230 227 .591 .571 112

or
2 being mti Z1 236 236 .585 .585 112

My mods are full exhasut, lid,k&n air filter , and built 4l60e with a viganlte 3200 stall.On motor my car put down 353 to the wheels. Then feature mods will be 100-150 shot of nitrous. And 90 fast intake and 90 nick willams throttle body. Which cam will work better with my setup?

 

neither. With nitrous you will need a cam with 4-8 degrees (8-10 degrees being optimum) more exhaust duration to allow the extra gasses from the spray to exit properly. stepped headers will help build more torque with nitrous as well. Id say you would be good with a cam like 224/232 on a 112-114 lsa, nitrous like a little higher lsa but you can use a loser lsa cam but your benefit will not be as great while on the bottle.
