Speed Inc 427ci HP #? I saw that Speed inc has a good deal on there website, they have a 427ci built motor plus install for $16K. Just wondered what kind of Horse Power u could expect from this engine. I know they dont give cam specs, but say u had something along the lines of 242/246 111 or something bigger.

right around 540 to the rear wheel is a good stab. could be 525, could be 560. plus or minus 20 though, depends on a lot of other variables. what rearend? auto or 6 sd? what size rims on the car.
