2006 GMC Sierra 4.8l. Already has tsp 220r cam, going to install on3 kit, low boost, 6-8psi. As far as fuel goes, planning on the Denso 1020 Fuel pump (280lph) and 60lb injectors. That sound about right for what I got?

Also as far as oil feed/return is concerned, im going to use the plate for the oil cooler from trick performance for feed, but for the drain, is there anything I can use that doesnt involve me drilling and tapping anything?
