LS1 Is 300
https://ls1tech.com/forums/conversio...ver-build.html
I just finished the same swap and have a full build thread. I used the T56 out of a firebird and the stock IS LSD rear end. I haven't had it together very long but so far no issues with the rear end. I do however have very little traction with the stock 215's.
Give that a read and if you still have questions feel free to PM me.
