Hey fellas does anyone know of a real good distributor hold down... mine is chrome and doesn't hold real well. I can get it tight and the timing is right on, but when I let the car sit for awhile after running it for a day or so it doesn't want to start right up like it normally would. Then when I check the distributor and it is loose again. I am guessing this is why the car doesn't want to start right up because the timing is off. Anyway the engine is a chevy 400 built with 425 HP. The clamp I have on there is a Mr. gasket chrome type. Any suggestions
