440source stroker kit around $2k or so, Trick flow heads around $2k or so, your choice of camshaft, intake and rockers. That would be about as cheap and effective as it gets.

In the end, sticking with all Mopar dimension parts in the crank and rods will cost you in both $$ and weight, which a stock block doesn't like. You could keep an eye out for a used after market crank with stock Mopar rod journals, grind it for a 2.2 Rod bearing and have a cost effective stroker, at least for the bottom end. Personally, I would look for a used 4.15 and go out to 4.25 + with the available 7.1 rod with 2.2 bearings and a .990 piston pin. This gives you 512 cubes, and a fairly light rotating assembly to help the block live. Better yet, if you stumble across a good crank with center counter weights, that is worth a lot of stress off the stock block as well. If you give us more details of what you intend to use this motor for, and the manners/power level you want, better suggestions can be given.

The absolute easiest and cheapest way is the reason Mopar made the 4.15" crank, but nobody builds them this cheap and easy anymore.
Just buy a 4.15" crank and find a decent set of stock compression height 72 and later 400 Mopar flat top pistons, bore your 440 from 4.32 to 4.342" (check me there for the exact oem 400 bore size) and use the 6.76" 440 rods. keep the cam mild and low lift ~.490" net lift or worst case you'll need to eyebrow the slugs a hair. The real reason mopar selected the 4.15" stroke size was to allow this oem based combo to work.
Assuming you can acquire all of the parts used you're only buying the crank and a rebalance along with some minor bore clearancing for the rod bolts which may take an hour with a dremel and less than 1/2 that with air and carbides.
Sure the bototm end will be heavier but the $$$ you save can be better spent upgrading the heads and torque is torque from there on out.
It's almost too easy to do it real old school if all you really want is more grunt. We're spoiled these days by inexpensive billet rods, back inthe day the heavy OEM stuff was all we had and we still won our fair share of battles!!!
400 blocks with low miles and good sets of reuseable pistons are still easy to find, guys will put down the heavy ( compared to a lightweight forged "kit" ) but the 4.15 stroke/6.76 oem rod/400 oem piston bobweight will still be lighter than any OEM 440 ever built by about 200 grams. you can lose more weight for free by taking the too long pressed OEM 1.09" pins and shortening them by 1/2" inch, old school hot rod trick used by Dick Landy back in the day.

I figured that was why the 400 pistons. This is good info for us poor boys. With this setup(4.15 crank,6.76 rods,400 pistons),where would that put the piston top from zero deck?

Streetwize's combo is a good option for you, because you want low speed torque and will wind up with low revs, if I read this right. Its' advantages are obviously cost. disadvantages are that it will use a big, thick ring pack and will lose some power there. Back in those days(60s to 70s) the ring pack was 50 percent of the power lost just to rotate the motor! It all falls back to speed costs $$, how fast do you want to go? If budget is really tight, then the stock piston deal looks great. If you want to upgrade the power level in the future, a set of H beam rods and forged pistons will set you up for potentially 700 hp down the road, just change out the cam and top end.
