OK, my timing chain has about 10 degrees of play in it before the rotor starts to move. I dont think thats normal, is it? And if not, how hard is it to change it, and the gears? I think the seal in front might be going bad also, sometimes I see fresh oil around that area. Should I replace it or does the chain being bad have anything to do with it? Also, how do I know if my Lifters are right? They make quite a bit of noise, thought it was cheap covers but some are more loose than others. Some I can move by shaking them and some are tight. Just curious if theres an old mechanics trick to adjusting them. Anyway, thought I would get some opinions on the matters. Thanks for any time and info.

The usual way to check it is to either put a straight edge on chain from crank sprocket to cam sprocket and push or pull against the chain so it moves away from the straight edge. The opposite side should be tight. The max allowable deflection is about 1/2 inch, IIRC. You can also do this without a straight edge by measuring deflection from a nearby reference point like a bolt or (if late-model) from a dowel pin.
Since timing chains are the life of your engine, I'd replace it if I was that far in and there were any questions about it. Replace the whole set with a roller set and you'd be good to go.
Hope this helps,
Daniel

I'd also replace the front seal while I was in...

So in other words, change it all. OK, is it hard to do the cam? I want to go up 1 more step, dont know the proper term. Then, I guess I should upgrade the lifters and everything to hold up, correct? I just want to save work down the road, if I can take care of it now. Do the timing gears change with the cam or they stay the same? I'm learning this as I do the job, so Please have patience if I ask a question you've heard 100 times already. Thanks for the response BornInAFord.

OK, heres what NPD has to offer. They have basic stock, Hyd. Then they have a 259/413 int 270/435 exh also Hyd, and then they have a Hyd version of the HiPo with the 298 Duration and 460 Lift, and they have the HiPo. Also, they have double roller timing chains. Any suggestions? Thanks for the time and info.

Always change the lifters when you install a new flat tappet cam. What do you want to do with this engine will determine your cam choice. If you use stock heads, stock cast pistons, etc. a monster cam is a waste of time and money. The Hipo version you listed would be more appropriate. Is you car an automatic or a stick? Does it have headers or a stock exhaust? What gear ratio do you have? These are all factors when selecting a cam. You can also contact Crane, Comp cams or any of the others and give them your info. and they will make a recommendation. They will also offer a matched cam kit to make sure everything is compatible. Cam lift, duration, valve springs, timing chain and so on.

Thanks Txbullfrog, all that info is on the bottom of these pages on my Signature. It has headers and its an auto C4. Stock heads, gonna a daily driver. Its got 2:79 on 14's, but I am getting some 225 60 15's this weekend, so I'll have those for the rest of the year anyway. I guess I'll call NPD and see if they have a kit for what I need. I think I'll go the Hyd HiPo, and what ever they perscribe to finish up the deal. Thanks for the time and info.
