Maddog13407 Posted January 31, 2011 Share Posted January 31, 2011 just bought an engine from the junkyard. came in a running 1980 r model valueliner. guy let me drive it before we tore it apart and took the engine and tranny out. has a 10 speed roadranger behind it. this engine has the big Mack plenum on the driverside with a two tube air cleaner. i knew it was a 300+ engine. got it home and it is an ETAZ673A. i looked at the front of the block by the timing cover and it says T675 no END or anything in front of it. I thought 675 was for a 237 so why does the tg riveted on the block behind the injetion pump sayin its an ETAZ673A? just wondering. Also the roadranger says its a RT1110. what exactly is this model? a 1 to 1 direct 10 speed? thanks, Matt Quote Link to comment Share on other sites More sharing options...
