Please read my post again...and with full respect to Keith....what I'm sayingis AT 427" , not at 482, or 514, or 557, (obviously torque and usually power goes up with displacement....even with less efficient heads) ...but for 427 CUBIC INCHES (the subject of this thread) in a Cobra, a small block is a more efficient package and an overall better power producer than a 427"
(4.233 x 3.78") FE...this is mainly due to the HUGE Variety of aftermarket heads out there for them.
