    BUICK 454/th400 swap

    I have a very clean 81 lesabre (it’s basically just a big g body 😁) that currently hosts a 350 that smokes like a diesel and a 700r4 that has a lack of 3rd and 4th gear. This winter I’m hoping to swap in a 454/th400 getting the motor and trans mounted is not my concerns, the wireing aspect...
