i may be a bonehead but i like to look at my 63 shop manual. you know what it says? 292cid= 280 ftlbs @ 1600 rpms, 3 7/8" bore, 4 1/8" stroke. 283cid= 275 ftlbs @ 2400rpms, 3 7/8" sroke, 3" bore. 327cid= 305 ftlbs @ 2000 rpms, 4" bore, 3 1/4 stroke.
not trying to throw out a bunch of numbers. the 292 looks to get .96 ftlbs per in2 at 1600 rpms, the the 283 gets .97 ftlbs per in2 but it has to turn 1.5 times as fast to get it! the 327 only gets .93 ftlbs per in2 and it has to turn 1.25 times faster with 35 more cubic inches!!!
well it looks to me like the ol 292 has more low end torque and well, i'll be, it has a 4 1/8 stroke. i wonder if that could have anything to do with it. maybe that and the heavier crankshaft (sorry just had to say it). so who knows what your torqe application is, but you might want to reconsider your bigger bore= more torque, per cubic inch that is. in the example above the bigger bore engine doesn't hold up so good. increasing rpms to get more torque will only work so far.
