Big Block Solid Lifter Cam

I am wanting to upgrade to a solid lifter flat tappet cam in my 49 Plymouth and am looking for a mopar performance cam. Specifically the .557 lift cam, P4120660 (P4120661AB is the cam and lifter kit).

As an alternate I may consider a comp cams XS290S which is .540 / .558 lift.

If you have one new or used and in good shape, that you want to sell let me know!

Thanks.
