Guest Posted November 1, 2003 Share Posted November 1, 2003 What was the correct factory redline for 1971 350 4bbl.? I'm probably going to order my guages pretty soon and I just want to make sure they send the right redline. Thanks! ------------------ Link to comment Share on other sites More sharing options...
72MC Posted November 4, 2003 Share Posted November 4, 2003 I believe it is 5000 for small blocks and 5500 for big blocks. - Dave Link to comment Share on other sites More sharing options...
