I can assemble a for 4.6 in one day, It takes me a few days to button up the longblock of a 911 if I have to check deck, piston to head, piston to valve, measure the main/rod clearances, and set the cams. What does a set of oem pistons cost for a 4.6? Compare to that to the cost of new mahle's. And as stated above, almost any body with a decent mechanical background can build an american v8 motor.An air cooled flat 6 is much more complicated, and there are a hundred more ways to screw one up. Parts cost more, just because of the laws of supply , and demand, and the fact that a lot of the stuff comes from across the pond. I could order a crankshaft ,and bearing kit for a 4.6 right now, and have it sitting in my shop tomorrow morning for less than $250.00. Try that with a 911 .
