Who has done a 5.7 with a833 4 speed Overdrive ?

The Holley FEAD setup is cool but too expensive for my blood. And (I think) the only time it would be really useful is if you wanted to run AC. Cost wise, I think a car TC cover would work fine, minus a notch to the frame rail flange for the alternator. You can run the car TC cover without the AC compressor, just takes a shorter belt.

It's what I wanted to do to my '15 Challenger R/T, 6.4 intake/cam/exhaust. And I figured when since I sold that car and was doing a 5.7 into a Duster, why not do the same plan for the most part. So I have a car 6.4 intake and cam plus Holley swap headers. I figure if it only get's me to 425 crank HP, in a lighter car it should be as fun as a Scat Pac

Ok great info there. I'll roll with what I have. Sounds like you have lots of options!

Right on! Sounds like we'll have similar builds. I'll see what I can do with finding a truck 6.4 intake. I think it will work. My strong suit is welding and fab so I'll see if I can cook up something to solve the cold air intake. I thought the same thing! I just got done building a snorty 383 for my wife's Dart and had $6300 in the motor. I can get that horsepower for less money and perhaps a bit more reliable with the 5.7 so that's why I'm doing this project for my Duster!
