This 500 ish hp 10:1 355 Chevy with tunnel ram only made 448 lbs-ft, 1.26 lbs-ft per cid. Obviously it don't mean much in itself, it did gain over the single plane and dual plane and 10 more cid and a little more cr would help but just bolting on a tunnel is still far off the 1.35-1.45 tq:cid in this case.
