You can use the stock rods and crank. If you're set to use new crank and rods, then might as well stroke it. Just add matching pistons.
Mileage isn't that simple. Same A/F ratio? Even at steady cruising, the same size engine with mods will be breathing deeper, displacing more air with every rpm due to improved volumetric efficiency. The result is greater power. With more air, goes more fuel, even at the same rpm and A/F ratio. The real advantage in mileage comes when you pair a more powerful engine with taller gearing to take advantage of the greater engine output. You can then turn lower rpm without overloading the engine and causing it to use even more gas. There's a sweet spot where you can couple greater power output with improved efficiency and will see improved mileage, with otherwise stock setup, but if you gear for lower engine rpm, you defeat the performance of the higher power engine for drag-racing, but your top speed would increase.....not really useful. You may see some mileage increase by virtue of having a more powerful setup that moves the truck more easily with less throttle, but that's probably it. If your peak power is too high, your mileage will drop because the engine just doesn't have the grunt where it needs it. A change in gearing will fix that, and actually improve mileage, but again, it's always a compromise.

So if im gentle and I optimize it for more torque and mid range powerband instead of a full out high RPM drag racing setup it MAY get better gas? and would 4.10 gears make it faster or slower for racing......

Ive been gathering a list of parts and so far I'm going with the Hughes 5409, HIP FR3, the edelbrock performer RPM heads and ill keep adding to the list as a move down the engine.....this won't kill the low end torque too badly right?

actually with newer more radical cam,better flowing heads and supporting mods you will be using more fuel than stock,as more power = more fuel.
you won't know till you drive it after rebuild,but you might be in the 10 mpg range or worse,especially if you "get on it".

Yeah, I'm afraid you're mixing two different worlds. You're talking about high rpm racing, but a goal of 400 crank HP. Is this a street truck, or will it be a strip-only rig? The Chrysler smallblock crank, etc are good thru 6,000rpm, and have been since the late 60's. Typically, high rpm racing antics and fuel mileage don't share the same circles. So, I'm just trying to narrow down your focus a bit. The parts you listed should amp up your torque production nicely, especially with a good cam choice, as well as really opening up the higher rpm HP production. 4.10 gears will make it quicker. At cruising speed, you will be spinning higher rpm's. Typically, that means higher fuel consumption, unless the mods have moved the most efficient rpm range up. See, it's like this. Say you get 15mpg at 2500rpm on a stock setup. Say the gear swap moves you to an engine speed of 3000rpm at the same cruising speed. This moves the engine above the sweet spot (for the stock setup), and your mileage falls. Add engine mods, and the volumetric efficiency improves, especially at higher rpm's. So, despite cruising at higher engine speeds, you regain some mileage (though typically not all). Focus on the mods, get the power, then tweak for mileage. For a street engine, go for all the low and mid-range power you can, and stretch it as far up the rpm range as it'll go.

Ok, goal wise i want a daily drivable but powerful engine with a strong torque band and good high rpm power. Fuel economy is secondary to having decent everyday drivability and high amounts of power when wanted (at the strip)

OK, so basically, you're looking at current street Hemi power. Starting with a 5.9, you basically just address the traditional choke points: intake and exhaust, and all that is connected. Intake, heads, cam, exhaust. A matching computer tune will make your goal a reality. If you're dead-set on a new crank, I'd be really tempted to do the stroker kit because of the displacement, and the easy torque increase that inherently comes with larger displacement, especially at lower rpm's. If money is an issue, pop for heads and cam. Get the stock intake modded (see kegger mod), shave the throttle body ridges off to improve flow. and get headers. A custom tune will top it off.

Would this work? Im looking something that can run on 92 octane and be highly reliable (at least 200k out of it before having to fix it again)

Or should I go for the 426? I have also already bought a full exhaust with mid length headers, H pipe, high flow cats and strait through mufflers and 304 mandrel bent stainless tubing to connect it all, plus chrome tips cuz they look nice.
