ok, did anyone care to ask why does he need them? I've never heard a chain going because as it stretches the tensioner tightens it. It would have to snap, but then that could result in a major engine rebuild. What's the reason with why you think you need new chains?
no, im not replacing the chains cuz of a problem, im just gathering all the parts i need for the camswap. I want as little slack as possible, so i just want to get new chains. do it once do it right. besides, im sure the stock ones arent happy at me, seeing how it saw 6+ a lot.

Stop Doubting Mr. Wilson.....................
He has proven time and time again, without a doubt, that he is the unparrelled king of being able to do things to a Mark VIII like no other person in history. It would not surprise me that if there was someone who was able to stretch Mark VIII cam chains, it is him. After all, he has been able to cause more problems in a low mileage MarkVIII than anyone else on this board. Don't worry Mr. Wilson, I got your back.

Hell, if I could find my invoice from 5 star ford I'd tell ya.
IIRC, two secondary and two primary chains, tensioners, new gears on the heads and on the crank were... I want to say in the ballpark of about 1200 dollars. I could be way the hell off, too.
Typically I call Maxx, we BS for a bit, then I tell him what I'm shopping for, he tells me yay he has the stuff or nay he has to order it, I thank him, and I hang up. He has my CC on file, and several days later, the stuff appears at my doorstep. So, generally I don't keep track of my purchases from maxx. I know he's an honorable guy, and he'd never jerk me around.

I have personally been in on 3 installs of cams on DOHC motors, all cobra motors in the past 4 months.
let me re-phrase that....
I've been on 2 installs of new cams and the un-installation and the re-installation of one of them back to stock. were still waiting on results on the blower cam cars dyno sheet.
the gains were minimal at best. 7Hp 41TQ on a turbo grind and lost hp and tq on a blower grind we think, SOP feels different, sounds cool but doesnt feel alot faster. low end feels the same, better in the midrange and a serious loss in the top end. but thats maybe tuning. Mod motors are not like ls1 / pushrod cars where you throw in a magic stick / systemax II and gain 70 - 140 Hp and its a saturday afternoon install nor is there buttloads of information and techincal reference to go to when you have questions. I've done with the help of a few freinds a cam, water pump, heads, upper and lower intake and injectors in a saturday after noon for my old 5.0
it took the better part of a day and a half to degree those cams the first time most of the day for the other ones. We had 1 of the 3 svt tech's in st louis doing the install and it still took forever.
BTW the manaual is off on how to do cams because the manual thinks your putting in ford OEM cams which have alot of ticks / reference marks and an extensive cam degree spec sheet that aftermarket DOHC cams dont have because they dont want to give away any secrets. They give you barely enough to do the install. so that made the job ALOT harder. Also you'll NEED TO INSTALL NEW VALVE SPRINGS. this is not a recomendation this is a requirement. That was another suck part of the project.
Depending on how agressive your grind is, you may need to change your stall.
Also you might as well get started on programming your own car because there are only a few tuners that will do a ride-along tune for cams, even less on the slow limited mark VIII computer.
DOHC motors have been out for over 13 years and there are less than a handfull of manufactures that make cam kits for these motors because the gains are minimal and for the work needed to do it and the margin for error is so high.
We used the stock chains and just used new tentioners. I've taken apart 93 mark with almost 300K and the to primary chains were a little out but still within spec and the small chains were just about dead on as if brand new.
