I ran the Comp 290/650 in my 3000lb all iron 440+6 bottom end based Cuda, 14x32's/4.88's/4800 stall/Ladders/coils.. albeit without really enough CR (10:1)as the planned 12.5:1 upgrade never happened but it still ran great, I liked it a lot, ticked over at 900rpm, seemed quite docile to me and it pulled really strong at the top end, I just needed more cyl head to make decent power, think you'll like it in your combo.
