I'd have to agree...the engine likes to make peak torque in the lower rev range. So a taller 5th gear tends to lose its push factor at higher rpm.

the big bore kit has just enough added poke I find to make the 2.6* ratios more accessible with less penalties/drop offs.

Im not sure how you worked out your ratios as all the sprocket ratio charts online put a 16/44 and 17/47 at about the same 2.75 gear ratio
