Modified cooling system through side of block

That thread by sanborn is an ancient one. I remember reading that one and also his oiling mods. Great info. I think those pics might be up on another forum. I will look.

Yes the thread by Sanborn is an old one but I recently discovered the same modification is recommended in the "How to build big inch stroker small blocks" book. I have never been able to see the photos that originally were postedd with the Sanborn thread. His oiling mods thread is one of the b st ones I have seen as well.
