OK, I'm ready to put my 833 OD behind the 426 wedge my my 64 Polara, so I'm just double checking one more time...what I need is a bigblock truck bellhousing, right? Any specific year/part number, or will any of them work? Are there any other mods or parts I need to perform this swap? Car is currently 833 with small register bh, so I don't want to open this one up. If anybody has a bh they'd like to sell let me know. Thanks guys.
