What size and stall speed do you guys think i need behind my 12:1 572 Hemi street/strip deal? I have been running an 8" Dynamic 5400 stall behind my 511 12.5:1 wedge on the street without issue. I'm not afraid of stall speed and dont want to give up anything and drive it on the street. I have been told by a few that most under stall their Hemi's. Been told Hemi's n/a dont make the torque of an equal wedge, sounds like they need more stall. Not sure, what do ya think?
