I wonder what folks think about this cam for a 400:
https://butlerperformance.com/i-2936...tegory:1272239
Butler/Comp Roller Cam (HR) 282/288, 230/236, .510/.521, 114 LS (Std Firing Order/ Std Journals)
"Fits between the 423 (mild) and the 433 (radical) Cams from Comp with wider lobe separation. Similar in size at .050" as a Ram Air IV except more lift. Also makes much power than the Ram Air IV with a broader power curve."
