880joe Posted November 23, 2021 Share Posted November 23, 2021 How many degrees difference is there in the offset key versus the straight key? Also does it advance it or retard it? Quote Link to comment Share on other sites More sharing options...
Joey Mack Posted November 23, 2021 Share Posted November 23, 2021 I believe its 3 degrees, and you flip the key to advance or retard the engine. The key is painted on the ends. red is for the low HP engine's 300HP and lower, the White end is for HP above 400... red is retarded, white is advanced.. jojo Quote Link to comment Share on other sites More sharing options...
880joe Posted November 23, 2021 Author Share Posted November 23, 2021 So is there 6 degrees difference in timing of 400 and less and over 400 Quote Link to comment Share on other sites More sharing options...
Joey Mack Posted November 23, 2021 Share Posted November 23, 2021 I think so, I guess I need to open my engine book and see what it says. but, yes it would be 6 degrees.. 300 and less are retarded 3 degrees, 427 and up are advanced 3 degrees, you just flip the cam key around for the setting you need, Im sure there is more info needed on this but , I can't think of it right now... Im sorry I dont have all the answers right now. jojo Quote Link to comment Share on other sites More sharing options...
880joe Posted November 23, 2021 Author Share Posted November 23, 2021 I thought that you needed to retard the timing on a diesel and increase it on a gas engine to gain hp. This seems backwards if I'm thinking correctly Quote Link to comment Share on other sites More sharing options...
Joey Mack Posted November 23, 2021 Share Posted November 23, 2021 yeah i'm not sure either. I would check the cam part #'s to see if they are different, for the different HP ratings.. I should know the answer, but I dont, or I forgot... Sorry 880Joe.... Quote Link to comment Share on other sites More sharing options...
theakerstwo Posted November 23, 2021 Share Posted November 23, 2021 You can gain some power by advancing on diesel but you retard to save the engine 1 1 Quote glenn akers Link to comment Share on other sites More sharing options...
Onyx610 Posted November 24, 2021 Share Posted November 24, 2021 Also retarding the timing on a diesel makes it easier to start and advancing the timing makes it harder. Typically when it’s really advanced. 1 Quote Link to comment Share on other sites More sharing options...
Mackpro Posted November 27, 2021 Share Posted November 27, 2021 Looks like it’s just 1 degree . Quote Link to comment Share on other sites More sharing options...
