Running a SM465 with a Gen3 is basically the same, there is only a few differences. 1st is flywheel I will be using a NFW1050 $55 bucks at o'reilly is it deeper and makes up the .4 offset and will mount to a standard 11-7/8 clutch. 2nd an LS7 pilot bearing P/N 12557583 to properly support the input shaft because of the .4 difference in spacing between the block and crank. 3rd 5qty M10x1.5x40 bolts to hold the bell housing to the block. Additionally I have a full write up of the SM465 swap attached to the old 350 on my blog
