I want to drop this v-6 in my base coupe and upgrade to a v-8 but idk what engine to drop in her, a 6.1 hemi or an sl55, and is there anywhere in Texas to have a shop do everything for you, lol, i dont want to have to do any work myself cause im lazy

and would i have to change the 6 speed or the diff or reinforce the frame? any suggestions?
