[QUOTE="americansteel, post: 13690886, member: 149471"] the 5.0 coyote makes 442hp at 6600RPM to me that seems maxxed out for a reliable mass produced engine that only displaces 302 cubic inches. with long tube header's the 5.0 makes 459HP at the stock 6600RPM. to get the 5.0 to hit 475hp a tune long tube headers CAI you're looking at 480hp possibly and it being a smaller engine the power will peak at 7000RPM. this also depends on air temp and altitude/elevation. 90% of street driven cars do not see 6500 nor will they see 7000 why make peak power at such high rpm when the driver will never spin it that high? only 10% of mustang buyers race their vehicles. you want reliable power? the smaller engine is not the way to go, more cubic inches and or forced induction. this is crank power.
