Yes sir, 1,000 miles was normal up until the early 50s, then higher compression(less blowby) and better motor oils pushed it to 3,000. I called ford because my '65 Mustang manual said I could push it more than 3,000. I got some engineer on the phone(you use to be able to do that if you had the time and somebody else was paying the bill), and his words were, "If you're not adventurous enough to get your money's worth, it's your problem." Set me back, because I can still remember his exact words.
Speaking of calling Detroit, I called Henry Ford II, person to person and they told me he was out of the office
, but they connected me to Lee Iacocca instead. Another time I called Chevy engineering to get the specs on a camshaft. The guy who answered said everybody was at lunch
, and he was a janitor, but he looked up the specs and they turned out to be spot on.
