?? Valve Lashing 273 ??

I have a very smart Mopar friend that has a slant 6 in his Dodge coupe. He slipps the alternator belt off and runs the engine till the temp gauge just hits the red zone. He then sets the valves at 0 lash and hasn't readjusted them since he built the car years ago. (and no burnt valve problems) The theory behind this is that if the engine ever gets this hot he will shut it off anyway. The valve clearance will never get tight enough to keep valves open. It works for him. I set mine at spec. (.013-.021 warm {not hot} and always have a little rattle. I like the noise because it's a character sound of HP 273's and solid lifter cams. toolmanmike
