Car runs bad after cams
There is nothing wrong with Cosworth cams and this rumor is going to come to an end.
Unless the LOWER timing cover is being removed and crank trigger, front oil pump gear and camgear marks are being aligned, you are not doing it correctly.
You need to remove the lower cover, accessory belt, wpump pulley and recheck the marks under the cover.
Just because the marks on the gears to valve cover line up, does NOT mean the car is "in time".

i don't think he is saying that the Cossie's are bad cams in general. he is referring to one of their earlier batches of cams for the VIII. there was an Error on cosworths part & the alignment dowel for the gear was machined incorrectly & would cause the cams to be "out of time/sync" even when installed correctly.
to the OP, first verify your on TDC, then you can reference the timing marks on the crank by removing the coolant resivour, compare those to your cam gear timing & that should show you if the belt slipped a tooth.
there is some "play" or variance due to slop in the belt & tensioners so it may not line up 100% spot on but of you see more than 2-3 deg off you know it skipped a tooth
The coolant overflow tank is not required to be removed in order to check the mark on the harmonic balancer.
The mark is NOT supposed to line up perfectly with the "T" either FYI.

Yes that is what I was referring to I overlooked that it was about the VIII'S

yeah i know we already put it back to TDC anda the marks up top and down bottom all line up perfectly... the car runs and sounds like it is out of time but everything is ;lined up the way it should be. I wasnt trying to get on here and bash anyone or say anything bad about cosi cams... hell i have them and love them... All i am trying to do is see if anyone has had anything like this happen to them and if it was possible to get one of those sets out of that bad batch b/c i remember when it happened...
Sounds like a timing issue to me. If it ran fine before and all you did was a cam install then you either have the wrong cams or you didn't reinstall them 100% correctly. Maybe your "experience" has you just going through the motions and not thinking about your install. Its easy to check TDC. Why not start there?

one of the biggest vendor for cossie sent me 2 exhaust cams. I end up installing just the exhaust. I even called them up and was told that the blue box was the exhaust side and the white box was the intake. I am still waiting from them.
I wasted my Saturday for this mistake and my tuners time. If they don't resolved this asap. I will f them @ SEMA show......

I understand that my man... all im saying is that my cams had the same exact label on them but were in a white box.
I am NOT trying to say that someone sold him bad cams at all.... And the vendor he got them from has helped me out in the past...SCOTT.....but i have checked over and over this car and i just dont understand what the hell is wrong... it runs and sounds like it is a tooth off... but it isnt... I dont know muich abvout tuning so i have no clue if it is just a tuning issue... but the fact remains that it IS possible that he got two exhaust cams or whatever.. or the dowels were wrong or something... mistakes making parts happens. We will just have to resolve it in the car first... The stock cams will be going back in in the next couple days,.
