You buy a camshaft sproket with three keyways. One for stock, advance and retard. I decided to retard it after all. Idles good, but I did a ton of work at the same time. Gas milage still stinks, but now I think I need to change or bang out my cat. Can't think of why I am getting 9mpg.

lol. yes. that's what all performance cars are running on the track. matter of fact, worn timing chains are highly sought after performances pieces. i think ive seen john force in the local junkyard a time or two, looking for one.
think about what you just said and what a worn timing chain does.
and with that ladies and gents, i'm offto hit the hay.

So according to your logic a worn out timing chain will give youBetter performance...

My truck has alot more power. But..
I also added a 50mm fastman, and did the plenum upgrade. Then new plugs, wires, cap and rotor. So yeah with all that it feels alot better. I have only put like 200 miles on it since. Runs great, smooth idle, no CELs. I don't know about my top end but it does rev up quicker. I did alot at one time though.

If you dont know what your doing, dont waste your time. You wont notice a diffrence. My purposes were diffrent than most of yours. dont waste your time. Remember, you cant get power for nothing. There is no magic button you can press or magic **** you can turn to make power. If you want power you have to invest real money. If you want low end power, get gears. Period end of story.

Retarded valve timing is desirable on track cars, but what you have to consider is that all of these vehicles have either high stall (Drag) or run at high rpms and don't ever idle below 2-2.5k (track). We're talking about heavy trucks that, stock,idle at 650 and stall at 1800 if your lucky. Generally speaking, advancing the timing will give you more bottom end grunt. These trucks shift at (IIRC) 4800 wot, so lets call bottom end 0-2400 rpm. It does all depend on the what exactly the specs are on the cam though. It could very well be that the stock cam is ground with all of those features in mind, so that by advancing or retarding may be doing more harm than good. Most performance cams are ground for the desirable rpm range, and therefore ground to be installed straight up.

You can get a lot better performance out of these trucks by tweaking here and there. Maybe not enough to take to the drag strip, but enough to make the truck a lot more enjoyable on the open road.
Enough about that, when you did your chain was it on a stock cam or a performance cam? Is the cam in the Indy's the same as in the regular 360's?

How do you learn if you don't ask questions?

you can notget a lot better performance by tweaking. get off of cloud 9, its not going to happen. the best youll get is something thats fit slightly better to your driving style. thats about it.
stock, yes its the same.
