451 Budget builds?

so keeping budget 451 in mind lemme ask this:
If i use a solid 440 crank turned down-
can stock 440 rods be used?
what pistons are recommended?

I love FABO because you guys always know the answer or have at least tried it

thanks all

it's best to use 440 length rods. check out the kb piston site for the correct piston.
