It's me again asking for your help. I have Autolite 86 plugs in my 276 Hemi and one has gone down, we don't get Autolites over here. The Engine runs great and I don't want to loose the reliability of it, I have done a cross reference but the results are ridiculous, at least 10 different grades of Champion plugs alone!!! The engine runs 4 97's that are all live on a mechanical pump so what plugs do I use? Also what fuel pressure should be good, it's a new mechanical pump? All answers are gratefully received.
geeez....thought there would be a full couple of pages.....was just looking at my Champion book I think that it listed AC46 plugs as standard in the tune up section?....Champion cross was J11 I think.... my Autolite plug book has - 1952-55 2 barrel as A52 55 4BL is a A52 56 4BL is a A42 57/58 4BL is also a A42 Champion cross is - A42/J12Y or J13Y.....A52/J14Y AC cross is A42/44S......A52/45S Bosch cross is A42/W125T6 .....A52/didn't see one now my "Motors" manual lists AR82 - AR52 - AR42 Champ is - RJ18Y - RJ14Y -RJ13Y Bosch is W95TR6 -NOT FOUND - W125TR6 have fun... lawrence
