What year truck do you have? What year 261 do you have? How are your engine mounts? Do you have the shorty water pump sold by Patrick's? Are you trying to run the stock fan? I wouldn't be comfortable with 1/8" clearance.
The engine mounts are a steel-rubber sandwich and are made to flex and dampen torque and vibration. IMHO, 1/8" is too little.

Rocinante, like Don Quixote, he is awkward, past his prime, and engaged in a task beyond his capacities.
