Hello to all.
Thinking of swapping out my 330ci motor and 2 speed Jetaway trans in my 66 Cutlass. Will a 69 olds 455ci motor with a turbo 400 trans fit in my 66 Cutlass? If not, what is the biggest motor that will fit in there? Will there be any other problems with doing the swap which I probably will not
think of... Any help/info would be greatly appreciated. Trying to do the research before I do something dumb and have to un-dumb it.

Thanks,

Vegas Bob
