A customer of ours and his son are big into nostalgia flathead ford racing. While dropping off another block that his son spends hours porting and polishing, he shared this video with us. We handle all machine work including pressure testing the block, grinding the crank if needed, align hone, deck and head resurface, bore and hone cylinders, new valve seats if needed and cut/blend seats, balance rotating assembly, cam bearings and assemble rods. The customer handles the final assembly. Most of their engines are 4 1/8 stroke & 3 3/8 bore with S**t crank and rods, and Ross pistons. They are spinning these up to 5800 rpm!
