Ya it does, prices seem low as well. Probably building them from core injectors or working injectors. Not sure how well he knows his injectors but theres alot of folks that build but workmanship is a big thing to me seen to many failures.
I know Casserly wont build cores had way to many issues with them, he is one of the best as well. Found to have less problems or rare problems with new ones. I would save the money. But like I said I dont know his injectors or his workmanship so I cant judge what he does or how he works them.
