If removing the vacuum pump, two (2) M12-1.75 plugs (GM 11546665) (ICT Billet SKU# 551298) will need to be installed into block-oil ports. There are 3 positions for maximum adjustment of engine (from OEM bellhousing position ~forward most position shown in photos~, Secondary positions are: 1.625", and 2.25" engine moved frontward) These swap plates will shift the crankshaft centerline up .725" above factory small block location. At ICT Billet we use GM factory specifications to determine exact mounting locations for the most accurate engine positioning. To re-use your factory Gen 5 LT A/C compressor (and air pump on truck engines) you will need to use the 1.625" engine moved forward position on the swap plates, than trim the swap plates back. **Note, this will most likely cause your oil pan to have interference with your vehicles frame (or steering linkage), with poor aftermarket oil pan options currently available.
