Blueprint Engine from Pace Performance

[Walkers52]

Hey everybody Newby here, just joined today. I am in the process of finding a crate engine for my 52,3100. I had a used 355 installed but it has some issues and the seller bought it back, thankfully. Any way looking at BP 355 TBI. I see lots of bad reviews for BP but mostly its some ones buddy that had problems. Are any of you running a BP engine? If they are so bad, how, why does Summit, Jegs and Pace performance sell them? Any answers would be greatly appreciated.
