i did a search and theres lots of info out there on this swap but none really answer this question specifically. I have a 1968 galaxie with a c6 and 390 and seen that a 460 with modified 390 mounts will work but what about the transmission? most swaps i seen involve removing a stock FMX tranny or something else and using an FMX crossmember turned 180 degrees and then using an F100 6cyl. 3 speed manual tranny mount, well, do i still have to do that since my car came with a stock C6? i know that the stock tranny wont work but will the C6 for the 460 bolt in to the existing crossmember and tranny mount? does my question make sense?
