Buschur Racing BF 272 Cams
I don't know why people would question that.. I had them overnighted from Buschur Raing to the shop that was doing the work on my car USP Motorsports. I wouldn't come on here and sell bogus parts.
Buschur does not recommend using these cams on a stock block because of valve to piston clearances.. but a couple of people have gotten away with it.. although, it is a warning.. but yes, you absolutely need a good set of valve springs and retainers for these.. preferably supertech duals or buschur duals.. good luck
never heard about the not using them on stock block I know many are doing it. I do agree with the springs and retainers though. I even ran them on the stock ecu along with mellon.
