Hubert_25-25 Posted September 5, 2019 Share Posted September 5, 2019 The firing order for 6 cylinder engines is incorrect in the above chart. The Buick firing order is reversed. The shop manual has it listed as 142635. Hugh Link to comment Share on other sites More sharing options...
Morgan Wright Posted September 7, 2019 Author Share Posted September 7, 2019 That's weird. It's the exact reverse. I wonder if the compiler of that chart just looked at the distributor, and didn't realize the rotor goes clockwise in the old Buick 6's, counter-clockwise in the 8's Link to comment Share on other sites More sharing options...
