If your cooling is up to par like radiator, good cooling fans you will not have problems. I have a 406 with aluminum heads making 500+ horses and i never have a overheating problem. In 95 degree weather this summer mine ran around 185. My brother drag races and has 3 406 motors and has no problems.These 400's are torque beasts. Be prepared...lol
