Take a pill and chill. No need to shout. I can hear you. Take a look here:

The 427R and the M-6007-D392 engines are the ones I have owned and I was speaking of. The 427R is forged everything. The M-6007 is a cast crank.
Besides the forged/cast non-debate, the two motors are night and day difference. Both in cost and performance. I've put a lot of miles on both of these motors. I'm not making it up. In my personal, first hand experience, you get what you pay for in both of these motors. If you don't agree, fine.
Have a nice day.
