Alot is going to depend on what your going to use the truck for???
I'll try even lower timing for the heck of it. I have heard from another source that a few ounces of tranny fluid in the tank does work. I'll try that too.
This is my only vehicle and daily driver. My (stock) 350 got busted from an oil leak while driving, and this engine was the closest solution to getting my truck on the road again.
