Old HP magnum 383-440 cam???

That's kinda the idea. I would rather have tire spin when I WANT IT, not when just trying to accellerate a bit. It got real dicey when we had the heads rebuilt, but with the shortblock getting a little tired it's better now. I gave up daily burnouts back in the 70s.........

Jim retard the cam , it'll move the powerband up , just make sure the springs in the heads can handle the extra RPM
