Sold my race car ran low 9s and bought a 2011 srt8 challenger. 6.4 Purchased a kenne bell supercharger and plan on pulling engine to upgrade pistons and rods. Probably do cometics head gaskets and studs. Question I have is what torque converter do you recommend for transmission? I drive it on weekends and to work sometimes so street friendly. Trying to get 600rwhp on the 392 pump gas maybe little methanol injection .any Suggestions on combo or things I need to do would be appreciated I'm new to the Dodge world.
