If I wanted to build the fastest Mustang that could go around corners I'd take an ecoboost in a heartbeat, MAP seems to think they can build 700+ whp out of it and the stock block blew when they were pushing past 500 wheel:

Mustang GT curb weight: ~3720
Mustang Ecoboost curb weight: ~3532
200 lbs lighter and $3k cheaper? Not exactly the worst deal of the century there.
As for the OP, someone has to keep the dealership finance people in business I suppose.
