I have a 406 motor in my 72 and i believe its just a bit too much for the street. Im considering some engine swaps and am wondering which ones worked best for other members on here. What all would I need in order to swap a LSx motor or truck motor in this car? I want to keep the driveability on the car. Would I need a custom length driveshaft? rearend? Im wanting to run the T56 6 spd tranny. How much am I looking at spending? Could this be done in a garage or would I have to take it to a shop? Any help is greatly appreciated.
