383 or 440 Dilema

Had A 440 sitting here to put into an Aussie A body Valiant, Then a 383 came my way and It made me think , What would be the best for the old girl . got all new suspension already there plus 8.75 diff. The first thing is weight vs stroke another is of course space for headers plug wires etc , Just got A manual reverse valve body for a 727 which I orginally purchased for a SB 360, But put a Lokar cable kickdown on Instead,

Which way would you go and why, Oh yeah Its street and strip probably 50/50 :burnout::burnout:
