I have a '73 Chevy Impala that has a 350 engine with a th-350 trannyI've always wanted a big block, so I shopped around and found a '78 Chevy Silverado 3/4 ton truck with a 454 engine and th-400 transmission that is in excellent running conditionI want to take the engine and tranny out of my Impala and replace it with the engine and tranny from the Chevy truckpeople I talk to say it is a easy engine swap as the Impala has mounts for the 454 and th-400 since it was an option back thenI am not a mechanic, but I do know cars and tools and have experience since I was a teenI have always repaired all cars I have owned, but never have I done a engine/tranny swap from another vehiclei don't want to spend $1500 to have my local shop do it, but would consider it if it is going to be a pain in the a$$!Questions: What am I getting myself into? Can this be done over a weekend? Should I bring this to a shop? Any issues you all forsee with this project?Thanks in advance!

Yes it will fit, might need different motor mounts but they will bolt up to the engine and frame of the carBoth engines are pretty basic engines with the exception that the 78 will have the HEI and Electronic Ignition Module instead of points and condensorYes it can be done in a weekendQuestion to you have plenty of tools and acess to a friend or two and a engine crane (aka cherry picker)? Have fun and enjoy the power house you have.
