I thought the 6L had the same crank and same stroke, but the only difference was a bigger bore and different heads and cam specs.


Double check with the other guys though because I'm for the most part ignorant to this.

The 4L80E will not fit in and will not work in your Z. I looked into it and it's not worth the money and hassle.

It can and has been installed in Fbodys. Well worth the hassle since you won't be poping built 60's left and right. You'd need a new cross member and a 4L60 to 4L80 harness adaptor, and I think some sort of spacer for the converter. However I wouldnt no bolt it up to a stock converter. Vig makes good 4L80 converters. If you do a search some good information should pop up.

My bad. When I looked into it over a year ago there didn't appear to be a way to make it work well, and pcm programming was also an issue. Yet another example of how LS1 technology moves faster than us carburator guys can keep up with.

Well i was hopeing tp just put the tranny in with that converter for a little while to see how everthing goes. Adn then i ordered a Transgo shift get. To go with it so that i dont have to do any of the wireing part off it. And i will just hook up the Lock up to a switch. But the wear thing is when i called www.transmissioncenter.net/ 4L80E.htm about it they said there was no way to get the lock up to work with a manuel valve body.

Contrary to what they're saying...you can get the lockup to work. One of the local guys..running a manual valve body 4l80 in a fbody...I know he has the switch the manually lock the convertor... When he first put the thing in..I was hearing quite regularly how he could go 1-2-3-4-lock the convertor....
