Jesus Rick, you're like a rabid dog!
Did I phucking well say that an FE and a Cosworth are the same?
I only mentioned the Cosworth to illustrate that low pressure isn't the bad thing that everyone thinks it is. Cosworth recommended 800 miles between rebuilds - which worked fine. Doesn't have anything to do with being smart.
Bearing clearances on that were about the same as I ran on my aluminum block 482 - .0025 - .0003
