I have about 6000 hours each on 737 and A320, about 4000 on BAe 146 and 1500 on Westwinds.
180 to 6nm and 160 to 4nm isn't a problem on any of them, unless very light (because you have a very low final approach speed, so you need to slow down more to make stability criteria) or a tailwind. (and in the same way, 190 at 7nm, 200 at 8nm, 210 at 9nm and 220 at 10nm all easily doable - just throw out the gear for that 10 knot per mile decelation on a 3º slope.)
I seem to remember (while ago now) the Westwind would give us 350 to 4 mile final,
Well ... FOUR miles is a bit tight !!
MMO into VMO for descent - which is M.765 into 360 knots, and hold that 360 knots to a 90º intercept on the ILS at 10nm was doable.
(Set up the VOR on the runway track - to give you 10º of lead when the needle moves - as soon as the needle moves, Bank 30º, thrust idle, speed brake out - which gives a good pitch up for the turn in a Westwind - then flap one at 240, flap two at 220, gear at 180 and flap full to cross the fence still at idle and slowing past Vref.)
