Need opinion

There is a ton to swapping in a V8 if you have none to start. Other items needed are transmission, rear axle assembly, driveshaft, exh manifolding and system, and brakes. Plus, cooling system upgrades. An elephant Hemi takes some special things too, like mmodifying the inner wells, K frame, and brake master cylinder. What effect are you looking for? Performance? a certain Elapsed time? WOW effect at cruise nights?
