Welcome to FBBO
nice Charger,
Just build the 383, if you just want like 500+ HP
can be easily done
if not an all out/or a race motor,
if you don't need every last hp
be just fine, be very respectable too
good rods & good balance, a couple thousand dollars in a decent stroker kit
crank rods bearings pistons rings
all specific for that build
like a basic beginers stroker/entry level but very capable
a 440 crank mains turned down to B block size/counterweights taken down to 7.125",
to fit with no clearance issues & internally ballanced, pref.
or buy/build a
431-437+ (440 crank 3.75" stroke 4.280" 0.030" to 0.060" over bore), Kit form
477-484+ (4.15" stroke 4.280" 0.030" to 0.060" over bore), Kit Form
489-496+ (4.25" stroke 4.280" 0.030" to 0.060" overbore), Kit form
bigger bore you go the more heating problems you could run into

or buy a short-block already done
Or put the factory 383, aside if your worried about #s crap
& build a different B-low-deck, like a 400 low-deck,
they are better blocks/better thicker main webbing
for extreme performance builds
