Not Ranked
I smell a rat. Do the math on the torque/hp figures...they're all off by .2 hp. Although not significant, it indicates an error. Someone not quite get the fudge correct?
Your motor is more likely to make the hp figures posted (although inflated) than the 4.25X4.25 motor with 10.5:1. What's your c/r?
At 4.31 bore, there is a reasonable amount of unshrouding that the 4.25 engine has.
The 4.25 motor is claiming over 760 hp! That's a LONG way from your 660. And the point is moot, anyway. You ain't puttin any way near that to the ground in any of these Cobras.
CSX is completely right.
And so am I.
