Guys, I have the Blueprint 351/427 with a Holley Sniper EFI and four into four pipes. Instructions say to weld a bung into the exhaust after the four pipes collect into one and before the muffler. It's a wideband sensor and that would put it on the outside of the body (see attached photo). I don't particularly like that and worry about clearance with the body.
Any photos out there on how you have done it?
Thanks, Don
