Ever bought a truck, JUST for the motor???

[lyrikz]

I just purchased a 71 stepside. It has the inline 6 in it and i want to swap that out for a 396 or a 454. I was looking around and found a 2 wheel drive suburban iwth a good running 454 motor in it. Can i pull the motor and trans and use that in my 71???

Every other project i have ever worked on was an import car, never any domestics. I am pretty knowlegable on reubilds and what not, but have no idea what fits in my truck as for motors?

Any tips as to what fits in what??
