There is a #4.... and a #5... and and and....
I laughed as I read that and remembered one swap, not in an old truck, where I was firing up the torch every few minutes and saying 'we don't need that piece' in order to make room for the motor to fit.
Interestingly if I think back to all the swaps I've built, that was probably the second most successful as I drove the completed car (Vega GT with a 327) as my daily for quite a while and then sold it to someone else who rebuilt my trashed motor and then continued to drive the car.
