408 blueprint motor 445 hp
My buddy at work installed a 408 last year in his dart.
He has had excellent luck with the Blueprint engine... I was actually surprised with all the crappy reviews, but he just runs it as a street cruiser burning tires.
It was a great deal for him, for one he does not no how to build a motor, two it has a warranty, his car is running good with decent torque.
He is a happy customer, and the price fit his wallet.
