The Ford Barn - View Single Post - Thanks for everybodys Help and advice my first Flathead build is done and running

With used rods .035 is about minimum for most engines except at higher speeds. With new rods, a little more. When I am asked I usually say .050 because most non-professional builders can't or don't measure clearance EVERYWHERE on the dome. I just want them to be safe and happy. The performance difference is minimal.
