Found these in a box of parts I got with my 65 442. Don't know if these fit Oldsmobile engines or not. I know that Kenne-Bell made a lot of parts for the Buick and Pontiac 455, not sure if they ever got into the Olds game. Looking for any information on these? Thanks for the help

 

Those are Oldsmobile, and yes, Kenne-Bell did branch out into Oldsmobile parts in the 1980s. The best-fitting Olds headers I've ever installed were a set I got from them in the late 80s and installed in my 70 W-30. Even cleared the clutch linkage with no problems.

 

Thanks Joe for the information. The crank pulley looks small, almost like an under drive diameter. I'll put these back into the stash now that I know they are Oldsmobile.
