Again I don't remember EXACTLY what we talked about but Jason provide the new oil pump and chain and Mike Norris had NO problems doing the install.
The car has run better than a timex for over 2 years and, except when I road race, dosen't use a drop of oil.
Best advise I can give is call Jason - he Knows his stuff and he's a really nice guy. Good luck.

this is funny. i bought it from texas speed. when i called back about my issues, they told me thy NEVER heard of any clearance issues and couldnt help me what so ever.. as for the balancer, its not hitting, i checked that for the third time, and yes its a stock balancer. the hub on the balancer is now .025 smaller than the smallest diameter of the pump rotor, i even lined the timing cover with playdoe this time installed it, removed it, and it is not hitting anymore. as for trash getting through the screen, its definetly possible. the pick up tube is too small in my opinion, so it looks like they made up for it by using a screen with larger holes. there is not much clearance in the pump casing, maybe .002. the holes in the oil screen are .025. it wouldnt take alot of particles to get in that pump and gall it up. / lock it up. i have had a few people tell me that they ran into this problem as well with a stock pump, not many though. i think that maybe there was a bad batch of timing cover castings and im just one of the unlucky guys who ended up with it. im sure theres alot of them, but not ALOT of people running a double chain, if you take into consideration how many ls1's were produced.

It appears that Comp also makes a single roller timing set for the LSx engines. I've no experience with that piece in particular, but I do have experience with their dry timing belt kits and have never had an issue.

AJ's motor not only had the 1/2 of slop but it also was rubbing on the oil pump pretty good. AJ's motor wasn't the first time we have seen this crap either. All but one have been nothing but 
Cloyes build a chain way back in the day 98 or so. We called them asked if they could tighten it up a little and they did. It is the chain that we have been using for years. No chain related failures that I can think of.
