Dan, WOW!!! 572 GM crate motor
10 years ago, who would have thought that GM would offer such a monster! Any idea what they're selling in the shops for?
Unfortunately, "fully legal" over here means a lot. Any 2003 Cobra now requires a brand new, 2003 spec factory engine using an unmodified factory computer, entire pollution equipment left intact from donor car, etc.
Lucky my car is a 2002 model
