    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.

    Funny, but ended up on the wrong post lol. I'll leave it anyway.

    - 410 is the largest displacement I've seen with a 5.7 stroker without taking the bores dangerously out way too far. 403 is oddly specific (closet Olds fan?). Install the stroker kit, save as much bore as you can; the more metal you take out the less stiff the block is. Those precious few cubic inches (or fractions of a liter) aren't going to make a measurable difference anywhere but in your own mind.
    - I would not use ANY RFE in this situation. It's gonna die.
    - Talk to your tuner, depends on a few factors like cam, plug heat range, compression ratio, fuel you're using, etc. Can't get on a forum and ask that general a question and expect accurate answers.
    - Gear ratio is a function of purpose; are you looking for a certain trap speed, towing ability, to compliment the cam choice, etc?
    - A good one. Are you trying to slow your accessories down, thereby lessening drag or you trying to speed them up?
    - Hopefully someone from the area will answer your last one.

    I would contact these guys. They have a lot of business. Lots of mopars, mustangs, and vettes in and out of there.

    Thanks for the help guys. I want to go 403 ci so that it’s a true 6.6 liter, but as you said Hemilonestar, it’s just a small preference.
    So, nag1 tranny for this setup?
    I will not be towing, and want gears that will go with the cam I get installed.
    Still confused about the over and under drive options…
