Thoughts/opinions on Blueprint Engines 408 stroker crate engine?

I think my comment came off wrong. My point is that I don't believe you will see any issues with the cast crank. The limits of this crank aren't just related to engine speed though. I'd say several people have pushed them past the rated rpm with no issue. It all comes down to how it's assembled and how accurate the machining is. I've seen in videos how nice BPE's facility is, and I would expect they have very strict tolerances on these engines. I understand having concern spending this amount of money on an engine though, I really do. Contact Johnny Mac, I'm sure he will set your mind at ease.
