Timing Chain
I have a stock 79 351m. I will be replacing the timing chain this weekend. A double roller is four timrs the price of the stock single replacement. Anyone run one of these on a stock motor. Any comments about this, I will be modifying the engine in the not too near future
Thanks in advance

I think that the problem with a "stock" gear is that it is retarded a couple of degrees. If you see that it has a choice of three keyways or something like that (to allow adjustment), then maybe it's OK.
I'm sure a tighter chain is better than a loose one, but I don't know if the double roller stays tighter longer or not.
Was that unclear enough?

I'd use the double roller chain set just to undue the retarding of the cam that the stock chain set has.By advancing the time that 4 to 8 dreg.'s it just might be worth the extra cost of the timing set for the extra boost to the pants you feel when you get on it.

hey guys
I have a 77 f150 w/400 and i have been considering replacing the timing chain cause iwas told it would open up the stock cam. How does replacing the timing chain affect gas mileage?
Thanks

if you get a single roller timing set just make sure its not the one with the plastic coating on it. I just tore down my engine and the plastic teeth had worn off and there was plastic inside my oil pan, it was jumping time and i think It helped fry my cam bearing.

Personally,
If your rebuilding in the not too distant future I would save the bucks and not go with the double roller till I did my rebuild...."Stock" usually only means from Ford..anything you buy from JC Whitney or Summit Racing will allow you to set the timing +4 0 or -4 and their pretty cheap. I wouldnt put a used timing chain in a full rebuild.
