expert help needed (my first post)

here's a few comps:

still a small bock, but nicely appointed. mid 20's

again a small block, but with a modern 6spd and vintage air. it's not perfect, but shows nicely. low 20's

here's a stroker BB nacho with an auto that looks pretty decent. this is probably about the closest comp you'll find. and again, low 20's

so, ask yourself is big block and manual transmission worth 10K more?
to me yes, but for the buyer i would assume no. also this interior is miles better than mine, i have a column shifter setup but i'm thinking of switching to a center one, i have all the stuff necessary.
