L67 swap into 2000 Buick Lesabre.
so the trans is going out in my 2000 lesabre custom and i figured if im swapping the trans why not swap both for the L67 and hd trans.
i have a buddy with a 98 gtp with blown motor and trans i can take parts off before he scraps it. My question is what should i take off his car for mine?
(pcm,wire harness,supercharger,etc..) Also what else will i need for the swap(parts list?) this is my first ever swap also. also basic performance upgrades?
