when i took it apart i lined up the 2 dots took off the chain and gears put the new ones on that should of been it right . but now it wont idle and has no power and knocks on orther site says too line up marks then turn one revelosion then put in dis i cant belive this ive done dozens of chains before and never had a problem none on a dodge truck ran great before this

Did you reset the pcm after you installed the new chain, if not discon the neg side of the batt let it sit for a few then recon and start the truck, the pcm my take a little time to relearn. If you have removed the dizzy or turned it you will need to have your fuel sync reset using a scanner.

I know when I changed my timing chain that when I put the new gears on the marks did not line up. The cam mark and crank mark were both at the 12 oclock position. It kinda threw me off but I knew it was right because with the keyways theres only one way for it to go on. With the timing marks lined up my rotor was pointing at #6 not #1.

Your engine is a four stroke engine, not two. There will always be two pistons near TDC. One is on the compression stroke, one on the exhaust stroke.
With the top cam gear dot in the 6 o'clock position, and the bottom crank gear dot in the 12 o'clock position, the #6 (not the #1) cylinder is about to fire.
Rotate the dots so both are at 12 o'clock. Now, take off the distributor cap. If the rotor firing point is even with the line on the plastic plate just below it, your timing is correct if it's 180° off, you hosed the chain install and got it backward.
If it's anything other than spot on or 180° off, you really hosed it and might need to degree the cam to fix it.
