That is correct, generally the LT4 with smaller intake cam duration, lower compression, and small 1740SC spinning at higher speed will deliver higher low speed torque (and power) and a flatter overall curve than a 2650 on the LT1.
This is exactly the reason I really like the 2650 on LT engines (1 or 4) it is just the perfect balance of a fairly strong low speed torque and pulls hard right to redline.
