Adding a cold air intake will increase HP at the flywheel and the RW's, but swapping out your 3.27's for 3.55's will add HP only at the RW's.
sorry, I still think in terms of 60's engine testing. You are correct, the accessories DO affect hp at the crank, SAE testing has changed 2x since the engines I worked on as a kid.

Woe to him who builds his palace by unrighteousness,his upper rooms by injustice,making his countrymen work for nothing...Does it make you a king to have more and more cedar?Did not your father have food and drink?He did what was right and just,so all went well with him. He defended the cause of the poor and needy,and so all went well...But your eyes and your heart are set only on dishonest gain,on shedding innocent blood and on oppression and extortion. Jer 22:13, 15-17
