i was reading on zzps web site that there bringing the 1' chain set back and is improved from there last design is this true and has anybody heard anything about this and when its coming out and how the improvements are on it

There are a few thresds on forums about this at the mometn. Looks like a couple guys and Stattima may already have the solution and are working to get production. ZZP stated in one thread that since some people were talking down their company that they might just pull out of doing it. Then later said that with all the projects on their list, it'* low on the priorites. It'* very tough to read into their site and what they say, since commonly it'* opposite things.

IMHO, the chain is the lat thing you need to worry about in a 4T65E. I have never seen one broken, nor even seen a picture of one broken. There'* alot more to worry about. Thats why I run a 4T80E.

I seem to remember Bill had one break. And it didn't end well. Not a lot of room for when the chain wraps around the input gear.

Snapping the stock dual 5/16" chains can damage things, but snapping a single 7/8" chain isn't detrimental. Paul from PRJ Performance says he'* seen one broken 7/8" chain, but often they stretch. Dave from Triple Edge Performance told me that on refreshing a 30K mile race trans, he replaced the 7/8" chain among other things.

As Jeff says, the chains aren't too much of an issue. Once you get into 400+ CHP, then you can break the input shaft or stock chains. One of Bill'* friends has a turbo Regal that snapped its input shaft but otherwise did fine with all the other trans internals - also stock.

To answer what I think the original post was asking, I have heard nothing but assume that if ZZP can get a really good 1" chain again, seeing as how the former 1" chain never stretched or broke, we'll be set. Especially if it'* better, of course.

The 15/16" that a local snapped (happened in his car, but not from his power)



Many people say the 15/16" will snap before it stretches much and that the 7/8 will stretch.

A 7/8 that I put in new and put less than 2K miles on.


Under my right foot ISS reluctors suffer issues. Doesn't matter if it'* bolted, or just the stock pins.



I demodded and sold the motor nearly whole to a guy. Mentioned that the trans would be the weak link. Hopefully he heeds that warning and doesn't try to enjoy the instant hit of power too often like I did.

If I were still in the game, I'd be aiming for a 4T80. Jeff is it fairly easy to program in say a 2000 Regal?
