has anyone used products from Blueprint Engines?

I'm thinking crate motor instead of reinstalling my 340 in my Dart. Has anyone heard anything about BLUEPRINT ENGINES?

I seen an ad in Mopar Muscle and they have a 408 Stroker for $3,599.99 Claim 375 HP and 460 Torque. They have a 30 month 50,000 mile warranty for street engines. Is this too good to be true?
