It might "act" smaller but it sure won't sound smaller. As my machinist puts it "76 deg of overlap is 76 deg of overlap" as is the case with the MP509 I have in mine.
Where the cubes help is that it will have bottom end torque. A 509 in a 440 is a stone without at least a 3500 stall converter and minimum 3.91 gears. My 493 was swinging the needle on the dyno big time at 1500 and was making 500 ft/lbs by 2000. The only reason I put a 2800 converter in mine was so it wouldn't smash the driveline when you put it in D at 1100 rpm. Other than that it just drove away fine with the stock converter and a 2.76 gear.
First and only time out it went 13.92 at 101 4800 lbs with me in it. That was with full exhaust 2.76 SG and a no traction 2.23 60 ft.
