What would it take to make 1.44 lbs-ft per cid ?

I decided to do some Google search on the 360's and I found a interesting build. Engine Labs built a 360 with stock heads with 2.02/1.600 with port work. 650 demon carb, air gap intake manifold and a xe268h cam. The best they got was 387 horsepower and 434 LbFt of torque. I tried to load the article her but I couldn't get it to load. I'm not saying that this is true or a fact. But if they got 434 from a mild 360 then I would think that getting the extra 91 Lb Ft shouldn't be hard to get.
Torque is extra hard to get, it's on a per power stroke basis so you got to get the most you can out of each stroke, hp can make up for a lack of torque by just spinning higher in rpm.

For most of us 1 to 1.3 lbs-ft per cid is the amount most are gonna get out of a displacement in this case a 360 = peak torque of 360-468 lbs-ft basically a low cr 2bbl to pretty hot 360. 1.40 lbs-ft to max effort 1.67 lbs-ft per cid is out of reach for most these are highly developed race engines. Which leaves 1.31 to 1.39 lbs-ft per cid very hard but possible if everything done right, generally if your getting above 1.25 lbs-ft per cid your doing pretty good which is peak torque of 450 lbs-ft for a 360.

Why I was telling you if you want lots of low end torque out of a 318 (1.25 x 318 = 396 lbs-ft) it's kind of hard above a certain point, more displacement is easier.
