cam timming
 

does anybody make a mulit indexing cam sprocket to advance and retard camshafts? for a 4.6 single cam. and wear would you measure lift? thanx roy

No one makes one that I know of. I'm not sure that you would really want to do that it the first place. These motors turn really tight tolerances and I wouldn't want to risk slapping a valve. As long as the timing is set straight up everthing runs hunky dorey, but get into advancing and retarding the cam and things get a little hairy. I have pulled an engine or two out of cars that the oil pressure dropped, which in effect advanced the cam about 4 degrees and every valve in those cars hit the pistons. Of course those were Stage 2 cams, but the point still stands. Hope this helps out some.

thanx but how does one know the timming relation of piston position to valve opening? and both cams are on time, WHAT happens when you mill the heads? roy

Well, not to sound condecending, but you can only go so far with the heads anyway. I'd be glad to look that up for you, but those aren't numbers that I know right off the top of my head. There is some play room, but again, I would have to look them up.

If you are looking for more power, honestly, you may want to look into getting a set of cams for your car. A nice set of Comp Cams Stage 2 cams run about $550-$600. Not as cheap as a 5.0L but not too terribly bad for the power gain.

Oh hey, I found out that Fox Lake makes the adjustable cam gears for these cars. I'm not sure of the degree of advance or retard, but you may want to look into it.
