I ordered my blp bx4 850 builder kit, I talked to Joe on the phone this morning & I will say man he is a pleasure to do business with, also he mentioned if I needed any help at all he'd put me on with one of his guys to help out. 5 star morning.
Just a heads up, Holley bleeds won't work in the BX4 main body. The threads are the same but the body on the BLP bleeds is smaller. I made a fixture to turn down Holley bleeds to work.
