Depends on your budget. Cool thing with 383 is you can mildly stroke it (431ish final CI with .030 bore with 3.75 stroke if memory serves) and stroke:bore ratio is still such that you can rev crap out of it and it will pull like a monster.
Several places sell kits / cranks so no need ol school reqt of modifying 440 crank.
Not a "budget" build .. but not outrageous either.
