Then take .005 shim stock and place the shim under all the bearings during assembly. They make bearing spacers for 350 blocks and 283 cranks. They are basically a second bearing placed under the primary bearing. My 377 in my wagon was like that and I towed my car to the races with it and drove it for 11 years.
I would bet many have done this, including myself. When you are a toolmaker by trade, you shim a lot of stuff with no catastrophic results. That's why they make shim stock. Still, I'd like bearings unshimmed.
don't forget to put a hole in the shim stock for the oil flow. i have used steel shim stock for this purpose.
Not to bust your balls to much, but you realize that thread is almost 11 years old? The last comment was made March 27 2012? Why are guys doing this so much lately?
