I don't have the book but my guess it is from Blueprint Engines. I have not gotten any 1st hand experience but I should have bought one instead of rebuilding my 340 for the 3rd time
By the time I get done paying for the dyno time and rebuild I think I could have gotten the Blueprint engines stroker and mine isn't stroked.
I talked to them and they dyno each engine and claim to have built over 200,000 engines. They have a 30 month 50,000 mile warranty
For $3,600 + shipping I think it is a great deal. That engine isn't enough for you, they build more that that
