I want to swap a v8 motor in my f250, what will swap in place of a 300 6cyl without changing bellhousing or alot of other stuff?

 

Welcome to the site..

What year 250 are you working on?

 

1976 f250

 

302, 351w will swap without too much work..

Engine mounts, rad/shroud, exhaust, engine harness, throttle linkage, just to name a few. If your truck is a manual shift, you'd need the flywheel from the V8, 4.9 is weighed/balanced different.
