Guest Perk Posted May 11, 2010 Share Posted May 11, 2010 Can someone please tell me if the firing order on a 75 HEI is the same as all the other HEI caps, I have searched everywhere & cannot find anything on the 1975-455 with HEI distributor, I am installing universal plug wires & have a new cap also with the old cap sitting next to it and the firing order off manifold is not matching the way they had plug wires routed ? Yet I know it ran fine, Somethings different & I want to makle sure before I start cutting & crimping the new Taylor wires ? If anyone has a link for a 74-455 it would really HELP !!Thanks Perk Link to comment Share on other sites More sharing options...
Guest brh Posted May 11, 2010 Share Posted May 11, 2010 Firing order is the same for 74 (non HEI) 75 and 76. According to my Motors. Pass side starting at the fan--2468, Driver's side starting at the fan 1357. Hope this helps. Link to comment Share on other sites More sharing options...
