I just bought a 72 lemans tempest, it drives ok but it sounds like the motor is too loud to be going as fast as i am like if im going 50 it sounds like im going 80 or faster, does anyone know why? another thing, if im at a red light and try to burn out it, it will burn out as if im about to haul ass all the way down the road but it starts slowing down and acting as if it cant handle me pushing down on the gas like i am, why doesnt it keep going fast all the way through? it also seems like my accelerator is too close to the floor. what is the cheapest way i can make my car run better can anyone help me?
