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

Here’s how I see it, in practical terms…….

However much fuel that 408 was using to produce its peak TQ, you’ll need to use at least that much with the smaller cubes.
But without a dramatically different head/combustion chamber, you’re going to need to turn the smaller engine to a significantly higher rpm to efficiently mix that fuel with enough air for proper A/F ratios.

The two engines aren’t going to have the same power band.

I totally agree.

I'm just trying to figure out what it takes to build in the higher tq:cid ranges, cause ultimately I'm toying with the idea of building a mid/high 11's (don't want roll bar) 273 for my Valiant and like make peak under 7,000 rpms, more like 6,500 rpms if I can. Right now I got 360 380 hp crate.

Here's a 273/292 that makes 473 hp @ 7,900 rpm , but only makes 334 lbs-ft @ 7,100 rpm
Tq:cid is only 1.14 lbs-ft so lots of room for improvement.
