This job is quite a bit of work...of the top of my head the things you will need are:
-SC
-L67 heads and lower intake
-L67
PCM probably from a newer Monte SS
-Wiring adaptor for SC
-crank pulley at minimum if not all the accessory pulleys from the L67
-SC tensioner, and 2 idler pulleys.
-Vac lines for SC
-Probably a 2bar MAP sensor
....there is more I am sure...but just can't think of it.
