You do not need the lockup, I made my grand national lock when it hit second gear on up through the gears , it was awesome felt like a speed shift of a 4spd!! I ran kennebell cam ported heads big turbo and monster injectors it required a art carr torque convertor but man did people say wow when the first couple shifts hit!!! sorry i got off track but point is do what you want just know a convertor in non lockup creates a lot more heat than a locked one and that heat is wasted energy!!
