I have a 71 nova just got freshly painted tuxedo black.. running a 350 sb with a 200 4r trans I'm just about ready to swap this ls1 5.7 that I picked up a couple years back for a cool 7 hundo out of a 2001 or 2002 ss camaro .. just wanted to know the easiest way/ cost effect/performance way to go about doing it . Or if I should rebuild the motor first here some pics any info greatly appreciated
