Default GM DOHC plans, shelved in '08

Picked this up on another forum. I have no way to confirm it, but if anybody else has contacts in GM it would be interesting to ask them...It would appear the "LT5" designation was set for a comeback. Too bad the economy tanked and GM went bankrupt. Maybe someday.
