454 cooling question
My 454 is not running yet but it's .030 over and I dont want any cooling issues. I will be running one of Walkers Z series radiators but I was wondering if anyone recommends drilling the 3 lower cooling holes in the block to help with cooling. My engine is on the stand so would be easy to do. The heads already have the holes so I would think it would help, but is it worth the trouble.
thanks!
Could it be a 10114182? If so, it is a Gen V 454, 4 bolt 1991 (or later). Hope that helps..
