The owner of Fast Fieros
is working on it. He just did this car
, which was on Ebay a few weeks ago. He bought the Powerplants and transmission adapter plates from the Impala SS concept car. More info on this can be found here
There is also this guy
who put an LS1 in his.
I would love to have one with either the SIII 3.8SC mated with a comp-g tranny or the 5.3 mated with the same tranny... gutted, stiffened up, and caged... Track time would be awesome.
