How was your experience working with them? Are they true GM Marine Long blocks or are they building them?

I got 3 vortec’s from them and it’s my understanding that they’re the same thing as what Volvo and merc get right from GM, I did get a pre vortex piece one time, it had dart center bolt heads (. 8 bolt intake )... I believe that one they partially assembled themselves, ( using new short block and dart heads)
