What would it take to make 1.44 lbs-ft per cid ?
Here's basically a combo that closely accomplish the goal, problem is it don't really answer the question why/how ? It's vague what made this hit 495 tq and the W2 one only make 468 tq ?
It makes the same hp at the same rpm 515 @ 5,900 rpms but it's a bit shy in the torque department 495 tq @ 4,800 rpms vs 526 tq @ 4,000 rpms, The 371 is making 1.33lbs-ft per cid, would've been 1.37 tq:cid if was a 365.
