The 350 would bolt right in, unless the l6 you have now is a 292. Measure the lifter covers on the side of the block and if they are close to 6 inches high, you'll need the passenger side motor mount bracket. Shouldn't be a problem putting it in as the frame is already drilled for it. You might also consider getting a wiring harness for the engine to save cutting and splicing wires.
