any problems fitting small block 727 tran into 69 cuda

I had to modify dipstick tube, but thinking back, maybe all I had was a 904 tube, cant remember. Either way I just cut off mount tab, rotated tube and retacked. 67 car, should be the same. and I think the NSSwitch plug was different also. I believe you`ll need a large yoke and larger driveshaft built to size and balanced. thats about it. I`m rowing my own now so this is many years ago. If I missed anything, help em out guys8)
