Hi all. My son has restored a '51 GMC pickup that has a 270-cube straight six (apparently an option or replacement engine). He wants to adjust the valves, and while we have tons of car books, we have no reference for the specs on this truck. If anybody can help with the numbers for valve lash etc., we'd sure appreciate it.
