I have a 2005 Ram 1500 with the 5.7. I want to keep the original block and have it stroked out to somewhere between 400 and 403. I would prefer to find a mechanic local to Fort Worth to talk with, and possibly pay for some work. Questions: -I found a 400 stroker kit, can 403 ci also be achieved on the Hemis? -Can a stage 4 545rfe be used in this situation? -How much nitrous can be used with this setup? -What gear ratio do I need for the rear end? I currently have the 3.92 and plan to keep the stock original 20” wheels. -Which dampener do I need? Under or overdrive? -Which mechanics are trusted and near west Fort Worth/Azle? I used to be on this forum many years ago…glad to be back.
