Short block has just about 7,000 miles.
In excellent condition, never had any problems.
This short block just recently broke a 2v / M90 record of 434/401rwhp. Only reason for selling is that im going to a bigger 324ci. Decided to sell this short block while its still like new and worth money.
Here is one of the dyno pulls right before taking it out. Drove about 20 miles after this pull and pulled it out. No smoke:
Break in procedure was as follows:
It received 5 oil changes during the fist 3,000 miles, and followed all oil change recommendations as above. Then went to full real grade synthetic next oil changes.

The reason I didn’t go with a forged crank was because IMHO it is not necessary. The GT crank can handle upwards of 800whp, so unless you are planning to go beyond that, there is no need for a much heavier crank. That will be a result of some power loss. This lighter crank allows for a faster revving motor.
