Clearly both "can tear up the streets." But he's not building a vehicle around a motor (which is irrelavent anyway), so forget about body weight and all the other speculative responses. Yeah, sure there are plenty of well built 383's that can beat up on lesser built 440's. But as said above, with COMPARABLY BUILT MOTORS, a 440 will always out perform its little brother...the 383. No?
Sure it would! Equal parts, tuning and SAME chassis and a 57 cube advantage - VERY unfair, but an advantage. For sake of equality, trade off
57 cubes for 570 pounds LESS total car weight w/383 and the comparison just got a lot closer!! 440's are better to put into a mid to HEAVY chassis due to the torque they produce.
