Was just wondering if anyone is running one of the Blueprint Magnuson supercharged LS engines? Either the 376 or the 427. I was curious of the quality.

 

NA but very happy with quality and power output. dyno sheet reads 622hp flywheel

 

The 3 BP engines I've installed have gone in and worked well. Google has a handful of failures though

 

I'm extremely happy with my LS3 from BluePrint. Dyno'ed at 554hp. Not super happy with the 4L70 that came with it though. It all works, but I'm having some issues with it. I think they use gearstar trannies, which have a good name, but I'm having issues. Nothing major, but I'll probably have to have some work done on it. I will buy from them again. Next will probably be a manual though.
