im restoring a 73 challenger that had a 340 in it with a automatic 727 trans the old owner had it sitting in a field rotting away floor deep in mud so when i perchased it the block was in the passenger seat all turn down and the trany was next to it so im thinking instead of rebuilding the small block and going with a big block so do i have to change the k member to handle a 440 or can i use the original k member also will the trany mount up to a big block im hereing alot of yes and no's from the penut gallery i hang out with but they are chevy/ford people and i figured i will get the right answer from mopar guy
