We ran a blueprint 408 465Hp in the 70 duster I built with my dad, That car ran like a raped ape!! As soon as I am able to, I plan to buy 1 for my 1st gen truck and my 70 Duster build. Where else in the industry do you get a 50K warranty out of a performance engine that is bullet proofed like that. My local builder gives 6-month warranty. Any Joe on the street can assemble a stroker, but few will back it like blueprint does.
