You know it'd sure be easier if a good aftermarket W/P took care of this as the W/P would be a much easier install. Also I'd get a high flow 180 stat( drill a 1/16" hole in it for easy fillup). 160 is way too cool ex for a drag racer(& you are way above 160 degrees). The A/C condenser & trans cooler have to stay. I do not have the last word on fan advice but the old standby of a properly spaced(into the shroud) thermal clutch fan would be what I would do. there's just not enough air going thru the rad fins. EDIT yes that is the correct pump though I would check milodon & see if their pump is cheaper.
